Even without fusion, Gaia the Fierce Knight is a pretty solid monster to play as is, since it doesn't require any specific cards to do its job
Sure, the art, flavor, and creative interpretations of these characters as Magic cards are amazingand I can only imagine how much an entrenched comic book fan is enjoying them
