(continued): As for Marik's ace monster, I have no idea. I've seen some people claim it is Ra, but I don't know about that. Maybe he would take a page from his sister's book and have his ace card be a trap or spell. In that case, maybe Necrovalley? Who knows?
Thinking about it... I think his boss monster (assuming they don't go game-original and give him Hieratics or something) has to be Metal Reflect Slime. None of the remaining cards that could be acceptable make sense. It's not like Granadora or Humanoid Worm Drake's going to be it, and I doubt Ra or a variant of it would be either. (They'd have done that for Yami Marik if anyone.)
The problem is a lack of cards to give out. Aside from Yami Marik's level-up cards (most of which are tame enough one-ofs to still be plausible, but I won't mention them here), there's basically Granadora, Humanoid Slime/Worm Drake, Bait Doll, Meteor of Destruction, Tribute Burial and Vengeful Bog Spirit. Maybe a few things like GK's Ambusher or Cursed Fig could barely pad it out. But eh.
