3 Level 8 or higher "Myutant" monsters
When a card or effect is activated (Quick Effect): You can banish 1 "Myutant" card from your hand, GY, or face-up field, of the same type (Monster, Spell, or Trap); negate the activation, and if you do, banish that card. If this Fusion Summoned card you control is destroyed by an opponent's card: You can add up to 3 of your banished "Myutant" cards (up to 1 each of Monster, Spell, and Trap) to your hand. You can only use each effect of "Myutant Ultimus" once per turn.
