War chest? What are you talking about. All you've got is this simple, unassuming DECK OF CARDS.
Author commentary: The MC members all have a large receptacle for their gear, which is an object double for a deck of cards. The cards (items) fit into the deck (receptacle) the way a bunch of items (cards) would fit into a large receptacle (deck). Understand now? That's fine, neither does Clubs Deuce. Anyway, their storage receptacles are all these funny plays on words involving bellicose terms like war chest, battledrobe, etc.
