Pretty much its all the fun of building and buying packs for a competitive TCG deck but abstracted down enough to have a nice flow to it. Like there is literally a deck building phase where you are on a real time clock to buy, trade and sell cards all the while building your deck for the tournament phase where you play a abstract but still mentally engaging version of said card game. its full of goofy jokes and references. Its kind of a loving homage to its source material. XD
