I feel like it is weird that such a card game doesn't exist, but the regular cards are tied to NFTs instead
It just feels natural, you have gacha mechanics on the card packs, micro transactions (that can feel like macro transactions) for cosmetics and alt art, subscription systems for perks on match making (for battle passes, season passes, and grind passes for things like leveling up your cards faster to unlock cosmetics), the cards themselves are NFTs to be traded in an speculation based market, and the game-play itself is all in on economics references so crypto bros naturally will gravitate to it, but it is Yu-Gi-Oh
It is the ultimate scummy anti consumer game, that would get whales and coomers hooked on it, because all the characters are sexy anime girls
Take this idea, run with it, but don't give me credit, i don't want to go on living knowing i unleashed such evil into the world
