Yawgmoth, Thran Physician + Scurry Oak + Blood Artist

Yawgmoth, Thran Physician

Scurry Oak

Blood Artist

How it works

1. Cast Yawgmoth by paying 2.
2. When Yawgmoth enters the battlefield, Scurry Oak's evolve ability triggers.
3. Holding priority, activate Yawgmoth by paying 1 life and sacrificing a creature.
4. When the creature dies, Blood Artist triggers, causing you to gain 1 life and target opponent to lose 1 life.
5. Resolve the Yawgmoth ability, putting a -1/-1 counter on Scurry Oak and causing you to draw a card.
6. Resolve the Scurry Oak trigger, putting a +1/+1 counter on it, triggering Scurry Oak's second ability.
7. Holding priority, activate Yawgmoth by paying 1 life and sacrificing a creature.
8. When the creature dies, Blood Artist triggers, causing you to gain 1 life and target opponent to lose 1 life.
9. Resolve the Yawgmoth ability, putting a -1/-1 counter on Scurry Oak and causing you to draw a card.
10. Resolve the Scurry Oak trigger, creating a 1/1 Squirrel creature token.
11. When the Squirrel enters the battlefield, Scurry Oak's evolve ability triggers.
12. Repeat from step 6.

This looping engine turns simple creature sacrifices into an unstoppable cascade of value, anchored by Yawgmoth, Thran Physician's ability to turn life and fodder into fresh cards. Scurry Oak acts as the perpetual motion machine here, countering its own accumulated -1/-1 counters with fresh +1/+1 counters from its evolve trigger and token generation, ensuring you never run out of bodies to sacrifice. Meanwhile, Blood Artist quietly turns every single one of those deaths and rebirths into a fatal life-drain loop for your opponents while keeping your own life total comfortably in the black to fuel Yawgmoth's activation costs.
