Yawgmoth, Thran Physician + Scurry Oak + Vindictive Vampire

Yawgmoth, Thran Physician

Scurry Oak

Vindictive Vampire

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, Vindictive Vampire triggers, causing you to gain 1 life and dealing 1 damage to each opponent.
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, Vindictive Vampire triggers, causing you to gain 1 life and dealing 1 damage to each opponent.
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 delightfully vicious loop centers on Scurry Oak as a perpetual token engine, offsetting its own growth with Yawgmoth, Thran Physician's ability to place -1/-1 counters and draw cards at the cost of life and sacrifices. Whenever the Oak receives a +1/+1 counter, it creates a Squirrel token that triggers its own evolve ability to reset the cycle. Meanwhile, Vindictive Vampire sits quietly on the battlefield watching the carnage, turning every single creature sacrifice into a lethal drain of life for your opponents that effortlessly sustains Yawgmoth's life payment.
