I pulled it as a draft for a Progression Series of games with a friend. This may seem rather obvious, but can I use both of them that I pulled as substitutes for both of the materials for a fusion summon, or does it require that I use at least one of the real monsters as a part of it?

I am sure you can only use 1 of those substitutes, the rest must be the originals.

"but the other Fusion Material(s) must be correct."

And I need to read better.
