My idea for a game would basically involve a modified version of the Pokemon Trading Card Game (I debated between magic and yugioh as well but ultimately Pokemon is simpler to design for). Each player from each team would have their own card, with various attacks depending on that player's attributes - a high checking player would have powerful physical attacks that could penalize them in some way (take damage most likely), while a high passing player could allow for switching to a different active player and giving them some kind of benefit (a more powerful follow up attack). Instead of the energy used in the Pokemon game, each team would have its own currency of sorts. One of these cards could be played per turn, attached specifically to a player, in order to enable their attacks and other such abilities. It would actually be more interesting to me than the base Pokemon game due to the larger variety of teams compared to current energy types, though the number of attacks would likely be lesser with less information to draw from. We could also incorporate various tasks from the site into the game - a "Completed PT" card could upgrade a player's attack, causing it to do more damage.
