Rules Q&A | Battle Spirits Saga Deck Builder

BSS01-001

I have one life and this spirit [Ascends] using an ST01-003 Imperial Thunder Dragon Siegwurm when summoning it. Can I place four cores from the void into my life using its When Summoned effect?

Yes. You place cores from the void into your life until you have five life, so four cores can be moved.

I have one life and this spirit [Ascends] using another BSS01-001 Supernova Dragon Siegwurm Nova when summoning it. Can I place four cores from the void into my life using its When Summoned effect?

Yes, you can. The When Summoned effect activates since the spirit being used has "Siegwurm" in its card name.

When summoned, this spirit [Ascends] using a spirit with "Siegwurm" in its card name and I place only one soul core on it. Can I place cores from the void into my life by paying for its When Summoned effect with that soul core?

Yes, you can. This spirit will have zero cores and be destroyed, but the effect can be activated.

Placing a soul core from my life, my field, or my reserve into the void will allow me to place cores from the void into my life. How about a soul core from my trash?

Yes, it will. Even placing a soul core from your trash into the void can activate the effect.

Can a soul core placed into the void be placed into my reserve during my next core step?

No, it cannot. Generally speaking, once placed into the void, a soul core can not be moved again.

My opponent has two spirits with 4000 BP and one spirit with 6000 BP on their field. Can I destroy one spirit with 4000 BP and one spirit with 6000 BP using the When This Spirit Attacks effect on this spirit?

Yes, you can destroy those two spirits since their BP add up to 10,000 when combined.

My opponent has two spirits with 4000 BP and one spirit with 6000 BP on their field. Can I destroy only one spirit with 4000 BP using the When This Spirit Attacks effect on this spirit?

No, you cannot. Only one card is drawn.

BSS01-007

What is the meaning of "treat this spirit as LV3"?

Consider it to be LV3 even if it does not have the necessary number of cores placed onto it.

Does the effect on this spirit make it LV3 even if it has no cores on it?

No. All spirits are destroyed when the number of cores on them becomes insufficient for LV1.

If I have three BSS01-010 Oviraptodons and no other spirits on my field when I summon this card, can I reduce its cost by 6 and only pay 2?

BSS01-026

I don't fully understand the [Bloodcurse] effect?

If a spirit with [Bloodcurse] would be destroyed via comparing BP or destroyed by an effect of your opponent's spirit or similar, [Bloodcurse] allows you to place one core from your opponent's life and one core from the spirit with [Bloodcurse] into their owners' trashes to keep the spirit on the field refreshed.

If this spirit is LV2 and it removes a core from my opponent's life using [Bloodcurse], is that core placed into their trash or into the void?

Into their trash.

If this spirit remains on the field after activating [Bloodcurse], can I draw one card using BSS01-108 Rotting Swamp?

No, you cannot. When remaining on the field substitutes for destruction, effects with destruction as a condition do not activate.

If another spirit gains [Bloodcurse] from this spirit, can that [Bloodcurse] effect be activated even when the spirit is not attacking?

Yes, it can be activated. Spirits with [Curse] will possess [Bloodcurse] even when they are not attacking.

If a spirit with [Bloodcurse] is destroyed by my opponent while it only has one core on it, can [Bloodcurse] still be activated?

Yes, it can. In this situation, one core from your opponent's life and one core from the spirit with [Bloodcurse] are placed into their owners' trashes, after which that spirit goes to the trash rather than remaining on the field since it no longer has any cores on it.

Can [Bloodcurse] be activated on this spirit if it is destroyed after its BP becomes zero?

Yes, it can. In this situation, one core from your opponent's life and one core from the spirit possessing [Bloodcurse] are placed into their owners' trashes, after which the spirit goes to the trash rather than remaining on the field since it has zero BP.

BSS01-027

BSS01-042 Camelot Knight gains [Curse] from another effect while on the field. Can a spirit like that be returned to my hand using the effect on this card?

No, it cannot.

If the effect on this spirit causes another spirit to have zero cores, is that spirit destroyed?

Yes, it is.

BSS01-034

Do I even remove one core from each of my own spirits when this spirit is summoned?

Yes. Remove one core each from all spirits controlled by you and your opponent and place them into their owners' reserves.

If the effect on this spirit causes another spirit to have zero cores, is that spirit destroyed?

Yes, it is. Afterwards, place a core from the void onto this spirit for each spirit controlled by you or your opponent destroyed by this effect.

Can [Armor: Purple] protect against the When Summoned effect on this spirit?

No, it cannot. This effect does not rely on selection.

BSS01-035

If another spirit has both a core and a soul core on it when this spirit is summoned, which player determines which of those cores is removed?

No, you cannot.

If the effect on this spirit causes another spirit to have zero cores, is that spirit destroyed?

Yes, it is.

BSS01-040

If the effect on this spirit causes another spirit to have zero cores, is that spirit destroyed?

Yes, it is.

BSS01-047

If this spirit is blocked by a LV2 spirit and that spirit becomes LV1 following the block, can I treat the block as if it did not occur?

No. The block has already been established, so the battle advances to comparing BP regardless if the number of cores on the blocker becomes one following block declaration.

BSS01-048

If the effect on this spirit causes another spirit to have zero cores, is that spirit destroyed?

Yes, it is.

BSS01-049

If the effect on this spirit causes another spirit to have zero cores, is that spirit destroyed?

Yes, it is.

BSS01-051

If this spirit attacks while it only has a single soul core on it, can I pay that soul core to activate its When This Spirit Attacks effect?

Yes, you can. The spirit will then be destroyed since the number of cores on it becomes insufficient for LV1.

BSS01-052

When this LV2 spirit attacks, can I use the effect on ST03-013 HeavenPiercing Castle to place cores from the trash onto it?

Yes, you can.

Are all of my spirits with 3000 or fewer BP returned to my hand by the When Summoned effect on this spirit?

No, it does not.

BSS01-059

If I have two Dinosaur Harrier Turborexes on the field, what happens if I use their LV1-LV2-LV3 effects to select two of my opponent's spirits during my opponent's attack step?

If possible, one of those selected spirits attacks first this step. Following that, it is unnecessary for the second selected spirit to attack.

BSS01-060

Is this spirit able to block any number of my opponent's attacking spirits with 2 or fewer cores on them?

Yes. Unless destroyed, you can declare this spirit as a blocker any number of times while it is exhausted.

BSS01-061

Does performing a refresh step using the LV2 effect on this spirit allow me a second opportunity to refresh all of my exhausted spirits and move all of the cores from my trash into my reserve?

Yes, it does. Also, all effects which activate during the refresh step are activated.

Can I perform a second attack step after performing a refresh step using the LV2 effect on this spirit?

No, you cannot. After performing the refresh step you perform your end step.

BSS01-062

Can [Armor: White] protect against the When This Spirit Blocks effect on this spirit?

No, it cannot. This effect does not rely on selection.

BSS01-067

Can a spirit with [Armor: Red] gain [Armor: Red, Purple, White] from the LV3 effect on this spirit?

Yes, it can.

BSS01-071

If this spirit blocks while it has gained [Armor], can it be refreshed?

Yes, it can.

BSS01-072

When this LV2 spirit attacks, can I use the effect on ST03-013 HeavenPiercing Castle to place cores from the trash onto it?

Yes, you can.

BSS01-073

When this spirit is on the field, does it prevent your opponent's effects from removing cores from one of their own spirits that has a soul core on it?

No, it does not. It only prevents your opponent's effects from removing cores from this spirit or one of your spirits with a soul core on it.

If I control a Head Icemaid Fulla and a second spirit with a soul core on it, will my opponent's effects be unable to remove cores from either of them?

Correct. They will be unable to remove cores from either of the two spirits.

Can the effect on Head Icemaid Fulla protect against effects like the one on BSS01-125 Core Theft, which place cores into the trash?

Yes, it can.

BSS01-076

What is the meaning of "you may use magic cards in your hand without paying their cost"?

Your magic cards may be used without paying their use cost. They may also be used by paying their use cost, as usual.

Is it possible to pay 3 when using a magic card which costs 6 with 0 reduction?

No. You must pay the entire cost or not pay it at all. You cannot choose to pay only a portion of it.

While counting up yellow spirits and nexuses for the When Summoned effect on this spirit, can I include this spirit in the count?

Yes, it counts.

While counting up spirits and nexuses for the When Summoned effect on this spirit, can I include nexuses of colors other than yellow in the count?

BSS01-081

If a nexus is LV2 or higher, will it still lose effects active at LV1 in response to the effect on this spirit?

Yes, it will.

BSS01-083

My field is empty but I have four spirit cards with yellow symbols which cost 2 in my trash. Can I use those four symbols for cost reduction and only pay 4 to summon this spirit?

Yes, you can summon this spirit by paying 4.

This spirit has attacked and all of my spirits that cost 2 can no longer be blocked by my opponent's spirits that are LV2 or higher. Does that condition remain even if this spirit is then destroyed?

Yes. Even if this spirit is destroyed, your spirits that cost 2 cannot be blocked by your opponent's spirits that are LV2 or higher.

BSS01-084

The LV2 effect on this spirit prevents yellow spirits from being returned to my hand. Can they still be selected by effects which would return them to my hand?

Yes, they can. Once selected, however, the effect is resolved without returning them, since they are prevented from returning.

BSS01-086

What happens to the use cost of a magic card when it gains more reduction symbols than its original cost from the effect on this card?

The use cost is reduced to zero. Adding reduction symbols beyond the amount of the original cost will not reduce the use cost any further.

BSS01-089

My opponent has a BSS01-002 Divine Halberd Dragon Arc on the field and does not block the attack of this LV1 spirit. Does [Blessed] activate even though their life is not reduced?

No. The spirit did not reduce their life so it does not activate.

BSS01-091

What happens to a spirit when its BP becomes zero?

Spirits with zero or less BP are destroyed.

If I use the LV3 effect on this spirit to keep it on the field when it would be destroyed, can I then use the effect on BSS01-114 Blessed Cathedral to place a core into my reserve?

No, you cannot.

I have three spirits on my field, including this one. If all three of them are simultaneously destroyed, can I place a core from the void onto this spirit and keep it on the field, using its effect.?

Yes, you can.

BSS01-095

If the effect on this spirit has been activated, will LV2 or higher When This Spirit Blocks effects on my opponent's spirits no longer activate when they block my spirits with [Luster]?

No, they will activate. The effect is already activated and waiting to be resolved the moment the block occurs.

BSS01-099

What happens when a magic card gains more reduction symbols than its original cost from the effect on this card?

The use cost is reduced to zero. Adding reduction symbols beyond the amount of the original cost will not reduce the use cost any further.

BSS01-100

If this is the only spirit on my field, can I use its effect to reduce the cost of a BSS01-133 Angelic Pressure by 2 and only pay 1 to use it?

Yes, you can.

BSS01-101

If I have two of these nexuses on my field, can I draw two cards and discard one, then draw one more and discard one?

No. You must first draw three cards before choosing and discarding two.

BSS01-102

If this nexus is all I have on my field and I summon an ST01-003 Imperial Thunder Dragon Siegwurm, can I pay 4 to summon it after reducing the cost by 2?

Yes, you can.

BSS01-104

What is the meaning of "attacks first during your turn"?

It is the first spirit to attack after your attack step has begun.

BSS01-106

If the LV2 effect on this nexus is activated, when is the blocking spirit destroyed?

It is destroyed at the end of the battle in which it blocked, after battle resolution has been performed.

If I use the LV2 effect on this nexus while it has three cores on it, the nexus will become LV1 when one core is placed into the trash. Does the LV2 effect still activate?

Yes, it does.

Can [Armor: Purple] protect against the LV2 effect on this nexus?

No, it cannot. This effect does not rely on selection.

BSS01-107

If an effect on this nexus removes all of the cores from a spirit, is that spirit destroyed?

Yes, it is.

BSS01-108

Can I use the effect on this nexus to draw two cards when two of my spirits are destroyed simultaneously?

No. You only draw one card.

When I use the LV2 effect on this nexus to return one of my Serpent spirits on the field to my hand, can I also use the LV1 effect on it to draw a card?

No. When returning a card on the field to your hand substitutes for destruction, the draw effect does not activate.

BSS01-109

If this nexus is all I have on my field and I summon a BSS01-061 Mechabeast Fortress Naumanngard, can I pay 5 to summon it after reducing the cost by 3?

Yes, you can.

BSS01-110

If I have two LV2 BSS01-110 Infinity Motherships on my field along with a Mecha spirit, do I place a total of three cores into my reserve during my core step after adding two cores?

No, only two cores. This effect does not add to the number of cores you receive, it only changes the number of cores you receive to two.

BSS01-111

If my opponent draws two cards during their main step using an effect, can I force them to discard two cards using the LV2 effect on this nexus?

No, they only discard one card. If conditions for activating an effect triggered by drawing are fulfilled multiple times simultaneously, it only activates one time.

My opponent activates the burst effect on BSS01-118 Starblessed Draw then uses its main effect, drawing a total of four cards. How many cards must they discard if I activate the effect on Rocket City?

One card. They are drawing four cards all at one time using the effects on BSS01-118 Starblessed Draw, so the effect on this nexus only activates once.

BSS01-112

Does the effect on Forest of Steel Leaves prevent destruction by the effects of red spirits and all magic, or the effects of red spirits and red magic?

It prevents the destruction of White nexuses by the effects of your opponent's red spirits and red magic.

BSS01-114

If one of my yellow spirits is destroyed after an opponent's effect removes all of its cores, does the effect on this nexus still activate?

Yes, they activate because the spirit has been destroyed.

BSS01-116

If I have no spirits on my field during my start step, does the LV2 effect on this nexus activate?

No, it does not.

BSS01-117

I have three life and I use the effect on this magic card to change the cost on an ST01-003 Imperial Thunder Dragon Siegwurm in my hand to 3. Can I pay 3 to summon it?

Yes, you can. You can also use the reduction symbols on it to reduce the cost even further, since they remain unchanged.

BSS01-118

If I activate this card as a burst and draw four cards total using both the burst effect and the main effect, am I activating two separate effects letting me draw two cards each?

No, you are not. It is considered one effect combining the burst effect and the main effect to let you draw two cards then draw two more, increasing your hand by a total of four cards.

BSS01-122

Who chooses a spirit to destroy first, you or your opponent?

Your opponent selects a spirit to destroy, then you select a spirit to destroy.

Which spirit is destroyed first: mine or my opponent's?

They are destroyed simultaneously.

If my opponent uses this magic card and I have a spirit with [Armor: Purple] on my field, must I exclude that spirit when making my selection?

Yes. Only select from among those spirits without [Armor: Purple]. If all of your spirits possess [Armor: Purple], then selecting none is permissible.

BSS01-125

If the effect on this magic card causes a spirit to have zero cores, is that spirit destroyed?

Yes, it is.

BSS01-127

If my life total becomes zero, can I avoid losing by using the burst effect on this magic card to place a core from my reserve into my life?

No, you cannot. When your life total becomes zero, you have already lost by the time the burst effect on this magic card would activate.

BSS01-128

Using the effect on this magic card, can I select one of my spirits which is blocking and refresh it?

Yes, you can.

BSS01-130

What is the meaning of "that spirit can block while exhausted"?

The spirit selected when using the effect on this magic card can be declared as a blocker any number of times while it is exhausted.

BSS01-133

What happens to a spirit when its BP becomes zero?

Spirits with zero or less BP are destroyed.

BSS01-134

If a spirit is being treated as LV1 as a result of the burst effect on this magic card, does it remain LV1 even if all of its cores are removed?

No. All spirits are destroyed when the number of cores on them becomes insufficient for LV1.

BSS01-136

Do spirits summoned after the flash effect on this magic card has been activated have their BP reduced by 3000?

No, they do not. Only spirits on the field when this effect is activated have their BP reduced by 3000.

What happens to a spirit when its BP becomes zero?

Spirits with zero or less BP are destroyed.

Can [Armor: Yellow] protect against the effects on this magic card?

No, it cannot. These effects do not rely on selection.

ST04-003

Does the When Destroyed effect on this spirit activate when the number of cores on it becomes zero and it is destroyed?

No, it does not.

Do I pay a spirit's summoning cost when summoning it from the trash using the When Destroyed effect on this spirit?

Yes, you do.

Can I use the symbol on this spirit for cost reduction when summoning a spirit from the trash using the When Destroyed effect on this spirit?

No, you cannot. This spirit has already been destroyed and the card is on its way to the trash when the effect is being resolved.

ST04-009

Does "view the top four cards of your deck" mean I also have to show them to my opponent?

No, you do not have to show them to your opponent.

ST04-011

Can I draw a card when this spirit is destroyed in battle?

Yes, you can.

Can I draw a card using the effect on Freezstal when my cost 2 spirit is destroyed by [Curse]?

No, you cannot. Destruction due to [Curse] is destruction caused by an effect.

Can I draw a card using the effect on Freezstal when my cost 2 spirit is destroyed by magic during a flash window while it is participating in a battle?

No, you cannot.

ST04-012

If I return a destroyed spirit to my hand using the effect on this nexus, do bursts and effects which would trigger on its destruction activate?

Yes, they still activate even when the card is returned to your hand.

ST04-013

I control an ST04-013 Soap Bubble Lakeside and my cost 2 spirit and cost 3 spirit are simultaneously destroyed. If the effect on this nexus reveals a cost 2 card on the top of my deck, can I add it to my hand?

Yes, you can.

ST04-016

What happens to a spirit when its BP becomes zero?

Spirits with zero or fewer BP are destroyed.

ST03-001

What is the meaning of "this spirit cannot be destroyed by your opponent's destruction effects or as the result of battle"?

It means you ignore effects that explicitly say to destroy the spirit, and you do not destroy the spirit after comparing BP during battle resolution, even if it has the lower BP.

After losing one life during my opponent's attack step, I activate my BSS01-127 Absolute Ice Shield burst, increasing my life by one. If I control an ST03-001 Divine Moonsky Beast Fanatech Elk, can I use the effect on it at the end of my opponent's turn to place one core from their life into their trash, even though my life total remained the same?

Yes, you can.

ST03-002

I block with a LV2 ST03-002 Greygarmr and my opponent uses a BSS01-133 Angelic Pressure during the flash window following blocking to reduce its BP by 3000. When the turn ends, will my spirit be destroyed when its BP becomes zero?

No, because all effects become inactive simultaneously.

ST03-004

Does the effect on Mechawing Duck activate when a spirit card returns from the trash to the hand?

No, it does not activate.

ST03-008

Can the While This Spirit Blocks effect on an attacking spirit be activated by the effect on this spirit?

No, because it is not a When This Spirit Blocks effect.

Will a When This Spirit Attacks or Blocks effect activate twice?

No, only once.

I attack with this spirit while it has two cores on it then use the LV2 effect on ST03-013 Heaven-Piercing Castle to place two cores onto it, raising it to LV3. At this point, can the When This Spirit Blocks effect on this spirit be activated by its other effect?

No, it cannot. The spirit must be LV3 when the attack is declared to activate that effect.

ST03-010

Does a spirit selected by the effect on this spirit never refresh?

It does not refresh during the refresh step of the turn following when it was selected. On later turns it will refresh normally.

ST03-011

Can I use the effect on this spirit to place a core onto a LV1 spirit which gains a When This Spirit Blocks effect at LV2?

No. You must confirm the spirit fulfills the conditions at its current level.

Can I use the effect on this spirit to place a core onto a spirit possessing a When This Spirit Attacks or Blocks effect?

Yes, you can.

Can I use the effect on this spirit to place a core onto a spirit possessing a While This Spirit Blocks effect?

No, you cannot.

ST03-012

Can I use the effect on this nexus to refresh a LV1 spirit which has no effect at LV1 and only gains an effect at LV2 or higher?

No, you cannot.

Can I use the effect on this nexus to refresh a spirit which has gained [Armor] from the effect on BSS01-067 Armored Dragonship Enterprise?

No, you cannot.

ST03-013

Can I use the effect on this nexus and pay a soul core to draw a card when my opponent adds a magic card to his hand from his deck using the effect on ST04-009 Grimoire Fairy?

No, you cannot.

When I attack using a spirit with a When This Spirit Blocks effect, can I place my soul core from my trash onto that spirit?

Yes, you can place up to two cores onto it, including both regular cores and soul cores.

ST02-001

If the effect on this spirit causes a spirit to have zero cores, is that spirit destroyed?

Yes, it is.

ST02-003

I attack with this spirit while it has a soul core on it and my opponent blocks using a spirit with two cores on it. During the flash window after blocking, the number of cores on the blocking spirit is reduced to one using ST02-014 Poison Shot. In this situation, is the block treated as if it did not occur?

No, the block remains valid. Since the block has been established, the battle continues to comparing BP even if the cores on the blocking spirit are reduced to one following block declaration.

ST02-004

If the effect on this spirit causes a spirit to have zero cores, is that spirit destroyed?

Yes, it is.

ST02-011

If the effect on this spirit causes a spirit to have zero cores, is that spirit destroyed?

Yes, it is.

ST02-012

When placing this nexus, can I place one core from one of my opponent's spirits into their reserve if that spirit has one core and one soul core on it?

Yes, you can. In this situation, the spirit's owner decides which of the two cores to place into their reserve.

ST02-013

I control an ST02-013 Purple Smoke Valley and attack using a spirit with [Curse], and my opponent blocks using a spirit with two cores on it. During the flash window that follows, I use ST02-014 Poison Shot to select the blocking spirit and remove one core from it. In this situation, is the block treated as if it did not occur?

No. The block has already been established, so the battle advances to comparing BP regardless if the number of cores on the blocker becomes one following block declaration.

If I attack with a LV1 spirit which gains [Curse] at LV2, will the effect on this nexus prevent my opponent from blocking using spirits with only one core on them?

No, it will not. The spirit does not possess [Curse] until it reaches LV2, so the effect on the nexus does not activate.

ST02-014

If the effect on this magic card causes a spirit to have zero cores, is that spirit destroyed?

Yes, it is.

ST02-015

If the effect on this magic card causes a spirit to have zero cores, is that spirit destroyed?

Yes, it is.

ST02-016

Can a spirit with only one core on it attack while the burst effect on this card is active?

Yes, it can. In that situation, after one core is placed into the reserve, the attacking spirit has insufficient cores for LV1 and it is destroyed.

If a spirit with [Armor: Purple] attacks while the burst effect on this card is active, must one core still be placed into the reserve?

Yes, one core must be placed into the reserve. The effect on ST02-016 Bloody Rain does not involve a selection.

ST01-002

Can I pay 4 to summon an ST01-001 Nebula Dragon Andromeda when all I have on my field is this spirit?

Yes, you can.

ST01-007

If I pay this spirit's soul core and it becomes LV1, can I still draw a card?

Yes, you can.

ST01-009

I attack with a LV1 Dragron Trooper and my opponent uses ST04- 016 Drowsy Fumes during a flash window to reduce its BP by 2000. Will it be destroyed at the end of the battle when its BP becomes zero?

ST01-012

Can I draw two cards when I reduce my opponent's life using a spirit with two symbols?

No, you cannot. It is still a single reduction, so you only draw one card.

ST01-013

If two spirits are destroyed simultaneously and one has my soul core on it, can I use the effect on this nexus to place all of the cores from the spirit with the soul core along with all of the cores from the spirit without the soul core onto the selected spirit?

No, you cannot.

ST01-014

Can I use the flash effect on this card to cause one of my opponent's spirits to gain 2000 BP?

Yes, you can.
