3-4 player multiplayer
All normal commander rules entirely unmodified EXCEPT
10 starting life
20 card deck
Each player starts with a fake card called Ascent to Waterdeep to in play that cannot leave the battlefield.
There is a Bilbo, Birthday Celebrant that exists outside the game for each player. If a player activates their Bilbo, they win.
Don't bother with lands
Inspired by the Descent into Avernus cube, this cube uses a custom card for its engine like Descent. Working name 'Ascent to Waterdeep,' the card has the exact same effect as Descent, but instead of losing life, players gain life. This creates easy synergy for every deck.
NOTE: This is probably broken as hell. Was a random brainchild and had to see how it would turn out. Haven't tested it yet.
