Evolution End Burst
Add 1 "Overload Fusion" from your Deck to your hand. If you Fusion Summon a monster this turn with "Overload Fusion", using 6 or more monsters as material, that monster can attack a number of times each Battle Phase this turn, up to the number of monsters used as its Fusion Materials. For the rest of this turn after this card resolves, you cannot Special Summon monsters, except with Spell effects. You can only activate 1 "Evolution End Burst" per turn.
