There are two victory conditions, which are listed below.

If a player is required to establish a condition that already exists, that condition is not established again and the new act of establishing is treated as though it never took place.

If a player is required to move a game piece from one area to that same area, or from one card to that same card, that movement is not performed and is treated as though it never took place.

If for any reason a player is required to perform an action zero times or a negative number of times, that action is not performed. A negative does not cause the opposite of that action to be performed.

When a card or rule stipulates choosing “up to” some numerical upper limit and no lower limit is specified, the player may choose zero.

There are six card colors: red, purple, white, yellow, green, and blue.

Some cards have multiple colors, such as red and blue, or green and yellow.

Annotations written in parentheses help explain or supplement the rules used by cards.

Flavor text is written in italics and typically located below any effect text. Flavor text holds no significance in regard to the rules.

The maintenance cost for a level is printed below and to the right of that level.

Most cards have a card number printed in the lower right corner. This card number displays what card set (booster pack, prebuilt deck, etc.) the card belongs to, as well as the card’s individual number within that set.

Card rarity is printed to the left of the card number.

Card copyright information is printed in the lower left corner of the card.

The name of the card’s illustrator and/or concept designer is printed along the right side of the card near the lower right corner.

When moving multiple cards to the deck area simultaneously, do so one card at a time. When multiple cards are moved to the deck from a public area, the order in which the cards are moved is also public.

Effect directives can be one of two types: immediately resolving or continuous.

Refreshed: the card is placed vertically in front of you with its top facing toward your opponent.

Exhausted: the card is placed horizontally in front of you.

A deck consists of at least fifty and no more than sixty Battle Spirits Saga cards. Each deck is limited to four or fewer copies of cards with the same name.

Effects worded to trigger "at the start of the step" activate now.

The player taking their turn is now given the opportunity to select from the following list of actions permitted during the main step and perform any of them.

Effects worded "at the start of the step" activate now.

The player taking their turn is given an opportunity to act. If no management remains unresolved, they may attack with their spirits, or declare an end to their attack step and advance to the next step. If they attack, a battle begins.

Effects worded "end of your turn" or “end of opponent’s turn” activate now.

After all management required at this time has been performed, effects which are only active "during this turn" or "until the end of the turn" become inactive. Continue resolving any additional events requiring management which occur as a result.

The turn ends, and the next turn begins at its start step with the opponent becoming the player taking their turn.

The player taking their turn can attack with one refreshed spirit on their field which they control. First, they exhaust the spirit they wish to attack with and declare their attack.

Effects worded "when attacking" or "when this spirit attacks" activate now. Effects worded “while attacking,” “during the battle,” or “during battle” are now active if their conditions are fulfilled.

Flash effects can be used during this flash window. First, the player being attacked is given the option to use one flash effect. They may also pass, without using one. Regardless of whether the first player uses a flash effect or passes, the second player is then given the option to use a flash effect. End the flash window when two passes are declared in a row.

The player being attacked can block with one refreshed spirit on their field that they control. First, they exhaust the spirit they wish to block with and declare their block. If no block is declared, the battle advances to battle resolution and the flash window following blocking is not performed.

Effects worded "when blocking" or "when this spirit blocks" activate now. Effects worded “while blocking” are now active if their conditions are fulfilled.

Flash effects can be used during this flash window. First, the player blocking is given the option to use one flash effect. They may also pass, without using one. Regardless of whether the first player uses a flash effect or passes, the second player is then given the option to use a flash effect. End the flash window when two passes are declared in a row.

The result of a spirit's attack is determined during battle resolution. If the spirit was blocked, advance to comparing BP. If the spirit was not blocked, advance to applying damage.

Comparing BP

Applying Damage

Effects worded "when the battle ends" activate now.

Effects worded "while attacking," “while this spirit attacks,” "while blocking," “while this spirit attacks,” "during the battle," or “during battle” which were active while the battle took place become inactive.

The player taking their turn is now given the opportunity to perform their next action.

Activated effects are labeled either main, flash, or both main and flash. Effects labeled main can be activated during the main step of your turn. Effects labeled flash can be used during flash windows.

Some constant effects require that certain conditions be fulfilled in order to become active.

When their conditions are fulfilled, constant effects automatically become activeand begin continuously applying their effect directives.

Triggered effects have either a timing event printed in bold lettering next to their level or a conditional event described in their text.

Magic effects are labeled either main, flash, or both main and flash. Effects labeled main can be used during the main step of your turn. Effects labeled flash can be used during flash windows.

With immediately resolving effect directives, the effect ends after the directive is performed. Examples include "draw one card," "destroy all spirits," and "place one core on all of your spirits."

With continuous effect directives, the effect is active over some period of time. Examples include "all of your spirits gain 1000 BP during this turn," and "all of your opponent's spirits are treated as LV1 during this turn."

If an effect cost contains more than one directive, resolve them in order starting with the first directive in the text.

If additional effect costs are added by other effects, resolve them next.

The effect cost of an effect can only be paid if every portion of it is able to be paid.

If you cannot pay the effect cost, that effect does not activate.

Specify which effect you are activating. If the effect belongs to a card in your hand, reveal the card. If it is a burst effect, turn over your burst card to reveal it.

If activation requires a cost, determine what that cost is and pay it in full.

The effect now activates and enters a state where it is waiting to be resolved.

Resolve the effect. If multiple effects have activated and are waiting to be resolved, begin resolution with the most recently activated effect. When multiple effects activate simultaneously, the player taking their turn chooses one effect to resolve first.

If the number of targets is specified, you must select enough targets to fulfill that number. In the event there are not enough targets to fulfill this number, you must select all available targets, without being allowed to omit any eligible targets from selection.

If the description says to select "up to" a certain count, you are free to select any number of targets from zero up to and including that count. If the description says to select “any number,” you are free to select any number of targets including zero.

When the number of targets is specified but only a portion of that number is able to be selected, finish resolving the effect with as many targets as you are able to select.

When the number of targets is specified but none are able to be selected, that target cannot be chosen, and all effects associated with that target are ignored.

When you are required to select unrevealed cards from a private area with the condition that selected cards have specific information on them, there is no guarantee any cards in the area will have that information. Therefore, the player selecting is free to ignore any cards in that area which fulfill the condition. Unless specified otherwise, cards selected from private areas must be revealed in order to demonstrate they fulfill the conditions for selection.

Begin with all of the information as it is written on the card itself.

Apply all of the continuous effect directives which do not alter numerical values within that information.

Apply all of the continuous effect directives which do alter numerical values within that information.

Continuous effect directives not belonging to constant effects determine which game pieces they apply to when their effect is resolved.

Continuous effect directives which alter information on cards in specific areas are applied to that information the moment an applicable card enters that area.

In this case, the original event ends up never occurring.

If the event is a card or an effect, the player controlling that card or effect decides.

If the event is a particular action during the game, the player performing that action decides.

Interrupting gameplay management is resolved immediately when it occurs, even if that requires interrupting another action.

Checkpoint gameplay management is only performed at specific checkpoints during the game, and only after confirming that certain conditions are fulfilled. If the checkpoint is reached and those conditions are not fulfilled, this gameplay management is not performed, even if the conditions had been fulfilled during the performance of some other action.

If during gameplay management multiple checkpoints need managing simultaneously, that management is performed simultaneously.

When the number of cores on a spirit or nexus has been altered by an effect and that spirit or nexus is destroyed as a result of the number of cores on it becoming insufficient for LV1, treat the card as if it were destroyed by the effect.

When the LV1 cost of a spirit or nexus has been altered by an effect and that spirit or nexus is destroyed as a result of the number of cores on it becoming insufficient for LV1, treat the card as if it were destroyed by the effect.

When the BP of a spirit has been altered by an effect and that spirit is destroyed as a result of its BP becoming zero or less, treat the card as if it were destroyed by the effect.

When the level of a spirit has been altered by an effect and that spirit is destroyed as a result of its BP becoming zero or less, treat that card as if it were destroyed by the effect.

When a spirit owner’s actions or cost payments result in a change of level or BP of the spirit, and consequently the spirit is destroyed as a result of its BP becoming zero or less, that spirit is considered self-destroyed.

Sometimes spirits and nexuses are placed into the trash from the field by rules or effects. This is called destruction. The destruction of a card is performed in the following order.

Check if any effects substitute some other management for destruction and decide whether or not to apply them. If some other management is substituted, destruction management ends and the destruction does not occur.

Destruction has been confirmed. Effects triggered by destruction are now activated and waiting to be resolved.

The destroyed card is placed into its owner's trash, and any cores that were on the card are placed into its owner's reserve. These actions are considered to happen simultaneously.

If neither player is able to end the infinite loop, the game ends in a draw.

If one player is given a choice to end the infinite loop, that player declares how many times they wish to perform the looping action. The looping action is performed that number of times, then ended with an action that can end the infinite loop. If the game state afterwards is identical to the state at the start of the infinite loop (all the same cards are in the same areas), reentering the infinite loop is no longer considered an option unless it is forced by a triggered effect or something similar.

If both players are given a choice to end the infinite loop, the player taking their turn declares the number of times they wish to perform the looping action, then their opponent declares the number of times they wish to perform the looping action. Following both declarations, the looping action is performed the lowest number of times declared, then ended, by the player who declared the lower number, with an action that can end the infinite loop. If the game state afterwards is identical to the state at the start of the infinite loop (all the same cards are in the same areas), reentering the infinite loop is no longer considered an option for the player who declared the larger number unless it is forced by a triggered effect or something similar.
