similar ignition effect to red eyes slash same amount of cards (if special summoning to your hand) but has the ability to set a powerful card as opposed to special summoning a warrior type monster when its destroyed. interesting to see if it will become higher than a teir 4 deck with combos between hammer shark, the new spell that lets you raise levels of your water type monsters while being treated as umi face up and the skill beatdown
