For a while, we ran a 30-40 card "1v1-only" maybeboard and swapped them with cards tagged "multiplayer-only" when we wanted to play 2-player games. In theory, this allowed us to tune the cube as needed to the size of our games. In practice, it was too time-consuming to search through 1000+ cards to find the swaps, and 30-40 cards didn't make a big difference anyway.
This update removes the 1v1 maybeboard and adds the best 1v1 cards to the main cube. It also increases fixing levels, reintroduces utility lands, shakes up the partners, and shaves several unnecessary commanders to combat legendary bloat.
