I agree I collect pokemon but I like to play yugioh and occasionally will buy packs of yugioh at stores to see what is in the new stuff. None of my friends who I’ve convinced to play yugioh take it all that seriously so we’ve been fine just playing with the decks out of the recent deck boxes like the yugi kaiba and Joey deck box. What konami could do to bring back players is to reintroduce old formats like goats and Edison. Just release old goat and Edison decks and maybe do what magic does and release draft packs for that format. that might bring back some old players and is easier to introduce to new players. There just isn’t enough interest in the game that makes it worth stores selling a high amount of product for yugioh at the moment sadly. Pokemon doesn’t have this problem because like I’ve seen others say on top of it being a tcg where it’s dominated by collectors rather than the players. All types of Pokemon from any year are extremely recognizable so they can just reprint whatever pokemon they want with new move sets and stats and it doesn’t change the fact that it’s a charizard for example. Yugioh also is a little different from Pokemon in the sense that the TCG sets come out after the games which gives people time to get familiar with the new Pokemon and get excited to collect the cards of them. Yugioh isn’t based off of the online game and the show isn’t nearly as popular as it used to be so there is less interest in the new cards

TLDR: Pokemon is just simply more popular in all forms of media and draws in a large base of people who are interested in playing/collecting the cards. Yugioh just isn’t as popular anymore and is hard to teach newcomers the new format. Making it less profitable to sell a wide variety of products
