Using the Bank

I'll answer these in order:

-There is no rule for when you must bank cards, though I would assume that players would like to first collect the nominal 3 Brawl cards before they do. You could shop for cards and then decide to bank what's left. It's really up to the player's discretion. The Pit-Stop is kind flexible when it comes to its order of operations.

-Negative. A player must wait a full combat round before the cards are converted into cash. So you will never see an instance where a player will bank a card and instantly use it to purchase something at the Pit-Stop.

-You can cash as much as you want, though you cannot enter the next round with more than 7 cards in your hand. If you have nine cards, for instance, then you must choose and bank two of them before proceeding into the next combat round.

-Well, you can't cash in the cards you just purchased because they take a full combat round to process into money. You could, however, decide to bank a card you just drew from the Pit-Stop, but again, it won't be ready to use until the next Pit-Stop.
