Kaiba in dc

Considering he's basically Yu-gi-oh Iron Man (in terms of wealth and technology) I'd say he'd do pretty well.

i mean, at full power he can summon a literally god and multiple space dragons to fight at his command. They arent just holograms in a real fight, only in the "sport game" version. any of the god card holders would be on the higher-mid level of power in both of those universes.
