Discard 1 card, then reveal 1 Fusion Monster in your Extra Deck; add 1 of the Fusion Materials whose names are mentioned on that revealed monster from your Deck or GY to your hand, except the discarded card, then you can add a second such card to your hand, if the first card added was a Normal Monster. For the rest of this turn after this card resolves, you cannot Special Summon from the Extra Deck, except Fusion Monsters. You can only activate 1 “Fusion Draft” per turn.
