240 card cube for a 4-player multiplayer draft. Each time someone wins, the winner gets to swap up to 3 cards in the cube (Best of 1 games only). Such swaps are protected until at least 2 other changes have been made to the cube. Swaps must maintain the singleton nature of the cube, must be vintage legal, and must not care about graveyard order.
