This card is ridiculously OP. Should have been made an UR in this box for sure. Can't be negated, and monster is immune to effects (ALL!) If you try to immediately hit their SS with any effect, they simply pop this card and it goes first in the chain....screwing you over every time.
@Anonymous is obviously that you only chain canadia etc using your toggle button when they activate sss nobody would be dumb to only activate their traps in the damage step against sss only idiots that never read cards do that.
