See, I think the issue is Pokemon players still dont know how
The main issue here is skill. Like I said, pokemon players rather wait to see what wins and just play that. I will say Pokemon players are more skilled than Yugioh players since we have to at least build our decks and read cards but I still see all too often players doing what someone else did.
You have it backwards.
Pokemon players don't build decks, they just netdeck what wins because everything is affordable. Only top players stay ahead of the curve with deckbuilding and often times, it gets to a point where it is only a couple of cards.
In yugioh, deckbuilding is essential for even the smallest local event. Not knowing how many disruptions you mathematically need and which of those need to rotate in/out of main side deck is a deckbuilding complexity pokemon isn't even close to having.
Deckbuilding in pokemon is very forgiving as the game isn't frenetic and usually you can spare a few turns, in yugioh a poor opening means scoop phase. Bad ygo players blame the game usually, but their #1 sin is poor deckbuilding.
Also, yugioh has actual player interaction and not limited interaction like pokemon does. In pokemon, you can stop playing attention during your opponent's turn, go to bath and just check everything in the board, number of cards in hand and what's in the discard pile before he attacks and you are good.
In yugioh, you have to play close attention to your opponent because he can interact with you at any point of either player's turn which makes the game much more complex and requires more skill. Outplaying an opponent is way too complex for the average player in modern yugioh; pokemon 2024 is much more comparable to 2005 yugioh in terms of skill and startegy (skill is gradually winning card advantage to develop a better board than the opponent).
Moreover, the cost of top tier is actually a barrier for meta representation in ygo as people are often forced to play something else, which forces them to deckbuild better or they will get demoslished; also naturally limits netdecking in smaller locals. And don't even get me started in the insane sequencing Yugioh needs: pokemon sequencing is really basic.
Also, the "read card" comment is quite ignorant. Yugioh cards are insanely text intesive, because they have multiple effects and restrictions. A 40 card yugioh deck has comparable text to 10 60 card decks in pokemon. Just knowing your deck well, is comparable to knowing the full pokemon gauntlet in a diverse meta.
In pokemon you can read the cards in game, in yugioh, you have to memorize them, which is far more difficult.
Yugioh is way more complex and skill intensive than pokemon in pretty much every regard; game is actually having refreshing issues becasue of how complex it is (that's why rush duel and duel links formats were created).
Pokemon is a game whose main difficulties are finding the balance between early/ late game consistency and the widest toolkit available to compensate towards the lack of side deck. No wonder Andrés Torres which is a top yugioh player that casually plays pokemon could qualify to pokemon worlds by just playing a few events and has even been close to topping regionals and he doesn't play pokemon a whole lot.
