This is a Sudden Death Cube.
Players start at one life. If a player causes a tie, they lose instead. All other rules apply as normal.
Two players grid draft the entire cube, then build 15 card decks. Expect to include 4 lands/11 nonlands in your deck.
Inspired by Chemslayer and BreadWedding.

A big update. Double the size, removed the treasure for going second, reduced the level of instant speed interaction and made life gain more difficult.
