An ability (
There are five types of abilities:
: Enter abilities occur whenever a SIGNI or LRIG first enters the field. Enter abilities without a cost are mandatory, while Enter abilities with a cost are optional.
: Action abilities can be used during your main phase by paying their cost. As long as you can pay the cost, you can use Action abilities any number of times.
: Constant abilities are always in effect. Some Constant abilities have conditions, like having a certain number of cards in the trash or having SIGNI of a certain class on the field.
: Automatic abilities trigger whenever a certain condition is fulfilled, such as whenever a SIGNI attacks or by having a SIGNI enter the field from the trash.
Life Burst abilities activate whenever the card with the ability is crushed from Life Cloth.
Additionally, some abilities have further labels, indicating a usage restriction or use timing.
abilities can only be used or activated once per turn.
abilities can only be used or activated twice per turn.
abilities can only be used or activated once per game.
abilities can only be used or activated twice per game. (The only card that uses this is Infinite Variety of Explosions.)
Your Turn abilities are only active during your turn.
Opponent's Turn abilities are only active during your opponent's turn.
Main Phase,
Attack Phase, and
Spell Cut-In abilities can be used during the specified use timing. Since
abilities can already be used during the main phase by default, an ability with the Main Phase use timing is paired with another of the previous use timings to indicate that it can be used during both.
Unless specified otherwise, abilities are only active when a SIGNI or LRIG is on the field. However, if a SIGNI's ability triggers when it is removed from the field (such as if it was put into the trash as a cost, or it was vanished along with other SIGNI), then its abilities still occur.
