>What kind of Yu-Gi-Oh deck would the KS girls use?
God, thats a tough one. i'll probably be off the mark for some but here it goes.

>Hanako
A flip effect deck would probably be fitting, maybe Ghostricks or Prediction Princess and a bit of bias tells me she might play Lyrilusc too.
>Lilly
If we follow the aformentioned "Evil in disguise" narrative, Dogmatika would be a nice fit, otherwise one of many spellcaster decks. Would be funny if it was Endymion of all decks too.
>Emi
UA and/or FA for the memes. A Synchro deck of some kind if we're talking serious. It still follows the speedy and fighting on narrative too.
>Rin
Weatherpainters or a handrip deck for the memes. Actually, maybe Ghotti or some generic hard control deck.
>Shizune
Any tier 0 deck really. Thematically, i think BEWD would suit her well too.
>Misha
Exodia, either Win Condition or the OTK variant.

Bonus:
>Kenji
SPYRALs for the memes and Monarchs for real.

>Oh man WHY does such a game not exist?
It kinda does. The Tag Force series does about all what you said and then some. You buy packs with the currency you get from duels, there's small storylines involving each character you meet in the game, there's also anime-exclusive cards that are playable, tournaments also take place, tag duels included and the best part of all "dating sim mechanics" You can increase your relation with characters by interacting with them, giving them gifts etc, earn benefits from it and team up for tag duels and such. I suggest you to look into those games, They started off in the GX era and ended around Arc V i think. For me, its Tag Force 5 since it runs on the format i first started playing the actual TCG and its, in my opinion, the best kind of YGO around, despite my dislike of Synchros.
