Beifong's Bounty Hunters + Pawn of Ulamog

Beifong's Bounty Hunters

Pawn of Ulamog

How it works

1. Activate an Eldrazi Spawn by sacrificing it, adding C.
2. When the Eldrazi Spawn dies, Beifong's Bounty Hunters triggers, earthbending a land you control.
3. The earthbent land will become a 0/0 creature and dies as a state-based action due to having 0 toughness. When the land dies, it and Pawn of Ulamog trigger.
4. Resolve the land's trigger, returning it from your graveyard to the battlefield tapped.
5. Resolve the Pawn of Ulamog trigger, creating a 0/1 Eldrazi Spawn creature token.
6. Repeat.
