>>58715850Yeah, in the Pokemon universe. They're clearly in a bizarro situation where reality is warped to be able to fight each other. Yugi isn't playing turn based, not sacrificing cards to summon stuff like Slifer, Ash is using multiple pokemon at once, using mega, gigantamax, z-move, Yugi is using his millennium powers to take away Gengar's gigantamax form, etc.
So, Ash should be able to use a Master Ball on an opponent that isn't a pokemon in this case. Same way Yugi can randomly draw 4 cards for no reason and use bullshit like his "heart of the cards" hax to summon Holactie
