This is a set of pre-constructed mini-decks based on the Jump Start sets. Each of these mini-decks is intended to be combined with one another mini-deck to form one forty-card deck to fight against another player with. This is not designed with any semblance of a competitive mindset, but rather to be goofy and create weird decks that might make no sense. Goblins and life gain? Snow and zombies? This cube is for those who liked playing Jump Start or have wanted to play Jump Start but don't want to keep spending money on packs.
This is by no means a definitive list of what you can and can't do, but rather what decks I've come up with that I think are fun. I encourage people who want to have a collection of Jump Start decks to build their own.
