It's just a goddamn cardgame, the fate of the world doesn't need to be at stake. If you can have a series about fucking Karuta and make it good, you can have a show about some fucker just going from locals to regionals to nationals in a card game.
Just one fucking season with some teen winning against meta decks with a table 500. Some person trying to get back into the card game scene after not having played it in a decade. The tale of that one cute girl hiding her power level who actually wants to play the game and not just be slobbered on by fat, stinky overweight players. A parent trying to connect with their child through learning the cardgame and enjoying it.
SOMETHING other than ridiculous "save the world" end games.
