All this ignores that Yugi can just reach into a bag of pokeballs and immediately top deck a team that would make Tobias blush, and NOT SO FAST every single vaguely smart choice Ash make with bullshit.
Think peak Johto bullshit where things could run up the hydro pump and oneshot with Tackle, or fucking Thunder Armor.
Every single moment of a battle with Atem is gonna be like that.
Oh, you used a quad effective Ice Beam on his Rayquaza?
NOT SO FAST, Ash. My Rayquaza uses Dragon Dance and then Extremespeed. This heats up the air, which is kept sealed because of Air Lock. The battlefield reaches such high temperatures that the ice melts and then turns to steam! And steam is a part of the air, Ash, do you know what that means? That's right, Rayquaza gains control of the steam, and sends it back into your pokemon, causing it to explode!
This, except for every single interaction
