Multiplayer commander with ALL the same rules except a 40 card, NOT counting commanders, non-singleton deck, and 30 starting life.
At the begining of each upkeep if there are fewer than 4 Heartbeat of Springs on the battlefield, one is created under no player's control. Essentially, after the first turn cycle all lands tap for five (5) mana. Have fun.
You must draft you lands as you would in a desert cube.

You may not play cards in commander sleeves in your main deck, or vise versa.
