20 starting life, no commander damage.
How to play:
Everyone is handed 4 commander options face down.
Players draft 25 cards. 5 packs of 10, pick 1 > burn 1 > pass.
Everyone's pools are shuffled together into a shared deck, then one card is removed facedown.
Each player picks their commander and puts it into their command zone alongside a Plains, Swamp, Mountain, Wastes, Goldmire Bridge, Drossforge Bridge, Rustvale Bridge, and Nomad Outpost.
Each player draws 4 cards from the shared deck, and plays a game of commander. Players may play lands from their command zone.
Additional rules:
Graveyards are not shared.
If an effect would have you search the deck, players are given 1 minute to do so. (Note to self, include a crappy board game hourglass in the box)
