@Hitsuji

Yeah a parody of the Yugioh series will be cool to see.

I not sure about the other Egyptian Gods (Probably renamed and redesigned to fit FGO and stuff).

Slifer the Sky Dragon will be one of them.

You can not summon them as servants given how they are essentially divine spirit (I assume that will be the proper term to describe them) and thus can only been seen as bosses you face in that event.
