This cube is meant to be for "board game night", so that if I have 4-6 people over, we can all draft and then play one big game together. As such, the focus is on multiplayer effects like Melee, Goad, Dethrone, Myriad, Encore, and Monarch. I have based most of the archetypes on the ones from Commander Legends so that the Partner Legends have as much support as possible. As a larger goal, every card in this cube should be under 2 dollars, with the majority under 1. To aid in deckbuilding, the Color Identity rule does not apply, and each player will be given a Command Tower in their pool. Players can use any cards they want in their 60 card decks, and then choose one or two commanders to lead the deck from that 60. Duplicates are also allowed.

Finally, with the release of CLB:
All instances of Partner may be treated as Choose a Background, and vice versa. All Monarch will be treated as Initiative OR vice versa. At the beginning of the game, players will determine whether they are playing a Monarch or Undercity game.
