[Auto]: Whenever this SIGNI attacks, your opponent may discard two cards. If they do, negate the attack.

[Auto]: At the beginning of your attack phase, you may pay (U)(U). If you do, turn target SIGNI in front of this SIGNI face down. At the end of this turn, if a SIGNI is not in the same position as the SIGNI turned face down this way, turn that SIGNI face up. However, if there is a SIGNI in the same position, put the SIGNI turned face down this way into the trash.
