Dark Contact

Activate 1 of these effects (but you can only use each effect of "Dark Contact" once per turn);
● Fusion Summon 1 Fusion Monster from your Extra Deck, that must be Special Summoned with "Dark Fusion", by shuffling its materials from your field, GY, and/or banishment into the Deck. (This is treated as a Fusion Summon with "Dark Fusion".)
● Add 1 "Supreme King's Castle" or "Dark Fusion" from your Deck to your hand.
