The Paper Pauper Battle Bag
the premise of these 17 decks is that they are all in identical black deck boxes, in a big bag. When you want to play a game (or even have a tournament of up to 17 players), you simply pick a deck out of the bag and play.
What I've done here is picked 5 mono-coloured decks, 10 two-coloured decks (one of every combination possible) and 2 four-coloured decks (affinity and Tron). I tried to pick the strongest strategies in Pauper as much as possible. That's 17 decks that I consider to be competitive.
Approximate cost of the Paper Pauper Battle Bag: $768.34 (deck boxes, sleeves and bag not included).
