Intended to be a multiplayer cube in the spirit of Commander Legends.

Players have three 20-card packs, each of which are seeded to contain two Planeswalkers. They pick two cards from each pack to create a 48 card deck, plus a chosen Oathbreaker and Signature Spell.

Unlike in normal Oathbreaker games, the signature spell does not have to match the color identity of the chosen Planeswalker. Instead, it adds to the color identity of the deck, allowing for 3096 possible combinations!

Players then play in a multiplayer game. Cube has capacity for up to 6 players.
