Honestly learning when a strategy isn't consistent is an important skill to develop here imo. If I lose the first round I'm out immediately and going back to drafting accomplices. If I lose the second I'll play one more to see which of the win or the loss was the fluke.
cod specifically is a terrible choice to be your only prep generator imo because she has only one the card. her big benefit is that she gets out of your way quickly.
