SIGNI during the phases of the game
During the main phase, SIGNI may be put onto the field from the hand on one of three unoccupied SIGNI zone. Also, once per turn, the turn player may remove their SIGNI, choosing any number of their SIGNI and putting them into the trash. Any abilities SIGNI may have can also be activated during this phase.
During the SIGNI attack step of the attack phase, before the LRIG attack step, SIGNI may attack by downing themselves. SIGNI that are already downed can't attack. If there is a SIGNI in front of the attacking SIGNI, those two SIGNI battle, and if the attacking SIGNI's power is greater than or equal to the other SIGNI, that SIGNI is banished. If there are no SIGNI in front of the attacking SIGNI, the SIGNI damages the opponent, crushing one of the opponent's life cloth, or winning the game if there is no life cloth.
