I suppose that I should also mention that sometimes, I card doesn't mesh well. Cocytus isn't a size 3, a size 0, a Wild Dragon, or has an effect that discards himself...while in Ancient World. He has some use, but very limited. In Parade, though, he is staple, because they can handle his stats and have the gauge for him.

Orthrus is similar. Wydar have more optimal size 2 monsters that would rather protect and give stuff and/or beat their face in with high crit. His pressure makes for a welcome addition in a fair number of Parade builds, however.

So yep, all about world restrictions and what each card has available to it, like how half of Darkheroes are HD, including most staples, but lack Schwarz.
