30 life points
Exactly 100 cards
On May 10, 2017, Magic Online launched tournament play for 1v1 Commander consisting of two-player queues and a Friendly Constructed League, and created a separate ban list for Magic Online Commander.
Players have a starting life total of 30. 1v1 Commander has its own banned list.
An important rule, which differentiates the format from any other Commander variant and option, is that you may only have one commander. Creatures with a partner ability function as if they did not have that ability.
