Future Fusion Question?

Question

I'm wondering if future fusion still works when only 1 fusion material monster is in the deck. What if the other is in your hand? Can you still use it? Or does it HAVe to be both fusion material monsters in your deck?

Answer 1

They all have to be in the deck and they all have to be "correct" Fusion-Material. No Substitutes.

Answer 2

has to be in hand :D

Answer 3

the material monsters must be sent from the deck.

Answer 4
