I tripled my dis-card via Coin Flip event with Temperance and a Get Well card in my deck. I also have a cue card, transit card, and some negative cards thanks to choosing diamonds and lucky shops.
So ... Temperance apparently caps at 1998 chips, but I have now farmed over 100,000 chips before the end of the Lounge and maxed out a birthday card from scratch in a single battle.
Love the game, try diamonds if y'all haven't already

Achieved the same thing more cleanly with pure cue cards and Temperance. This time I had credit cards to create negative cards and a Get Out of Jail Free card to nullify damage. I bought the entire casino and created inflation of +45,940,023,478%, which obliterated the global banking system and bankrupted all major exporters on Earth.
New floors will certainly come with some re-balancing.
