So basically, for Ash to win:
>you need to say that literally every feat performed in Yugioh is fake or not real (something DB has a precedent of not doing with episodes like Joker vs Giorno)
>you need to say Death Battle is going to massively scale Pokemon's lightning and building level explosions beyond Yugioh's lightning and building to outright fucking country sized explosions or even higher depending on what they buy for scaling
>you need to say that if they are buying universal tier wank for both of them that they would use the fucking insane VSBW reasoning that says that because the theme of the games (not even the anime, the GAMES) is 'infinite' that Ash's single '''''''''''universe''''''''''' feat is going to be better than the Yubel shit somehow
>you need to say that DB would go with the route that none of his cards would magically affect Ash even though they literally do affect monsters and even humans, as if this were deku vs asta levels of incongruous between the verses when they have equalized for far less like for gojo vs makima or tom vs wile
>you need to say Yugi just sits there like a fucking retard with his mouth open like most of Ash's opponents do in major fights he wins
>you need to say that Ash is totally going to bulldoze Yugi with his MFTL++ planetbusting physical feats he definitely has in spite of the fact he has literally never done this before even to people trying to kill him and also have to say yugi doesn't get duel armor even though the show he gets it from isn't really contradictory with his source material
Does that sum everything up?
