>>52803568While thats sorta true, if taken seriously the manga "Duel Monsters" especially the "expert rules" version that Duelist Kingdom used is actually extremely complex.
Its real world counterpart(Moncolle, which is to blame for the weird movement shit in only this one arc) is actually pretty hard to play and requires a lot of forethought.
Both the anime and manga show turns going past doing nothing so its not really that easy; most of it is just anime logic at work. So yeah if you want to think Ash can shit out solutions 24/7 then sure.
But he'd need to do this first try(most of the time he needs a lot of fucking time to even figure out a solution), and need to never interact with any sort of game of skill.
