theme decks aren't supposed to be competing evenly with constructed format decklists. that that does not happen is not a failing of the product, but the point. there is absolutely a ton of room for improvement in products like these, but the purpose of these products is that they are entry level decks that are meant to compete with each other first and foremost. i'd ask if you've forgotten what it's truly like to be new to a game like this, but chances are that was longer ago for me than it was for you. we've come a long way since the likes of Brushfire, that's for sure.
Local leagues aren't super competitive, and yet pretty much everyone has a meta deck in hand, if you play these, you are going to be stomped to death over and over. So this thing can't even do casual play.
Again, pokemon has a really big issue with card prices and accesibility but the other way around. Cards being too accessible kills any space for bad cards or decks to be experimented with.
Local leagues are also pretty much the obly way for some people to play physical pokemon as most stores don't even have "free play time" anymore as they have tournaments for a bunch of games running.
So what you are saying is that is ok they sell useless bulk product people won't even be able to re-use later to unsuspecting customers while penalizing retailers for it as "it isn't designed to be competitive" (which isn't the same as being designed to be super unplayable).
Who says it has or needs to be that way? Strategy isn't even consistent as if you start playing in PTCG live, you get a subpar version of a good deck more often than not as an starting point. Same applies to pre releases.
Also, if that is the point, that's what battle academy is there for. A product designed for toddlers as a board game.
Calling bad products bad and unecessary is the first necessary step to change something that is punishing everyone that dares to buy it. Who says a newcomer is better welcomed into the game with these unplayable piles instead of a lite version of a battle league deck or an structure deck with a theme like YGO?
