Dranch, Oudjah's lich lord

You don't lose the game if you have 0 life
If you would gain life, you instead mill that many
cards
If you would lose life, for each source of damage, sacrifice that many creatures or exile that many creatures from your graveyard. If you can't, you
lose the game
Ressurrected by Oudjah himself before he was killed,
Dranch roams the icelands, leading his cult to the
return of Oudjah
