The idea is that the game is supposed to be multiplayer, played in a small arena during multiple rounds, (I don't think I can make the multiplayer part for the jam).

Cards are destroyed once used, the player cannot regain mana in a round (expect by using some special card) The player can loot cards dropped by other dead players. At the end of the round the players left without mana and/or cards are given bonus mana and random cards, until there is only one left (it's basically a battle royal at this point 😁) or maybe the remaining players drop their cards and start a fist fight, I dunno
