Yawgmoth, Thran Physician + Scurry Oak + Ashes of the Abhorrent

Yawgmoth, Thran Physician

Scurry Oak

Ashes of the Abhorrent

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, Ashes of the Abhorrent triggers, causing you to gain 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, Ashes of the Abhorrent triggers, causing you to gain 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 clever engine loops by playing a balancing act on Scurry Oak's statistics, using its evolve ability and counter triggers to constantly replenish your board with fresh sacrifices. Yawgmoth, Thran Physician acts as the core catalyst, turning those newly minted tokens into card draw while trading life for -1/-1 counters that reset Scurry Oak's toughness. Meanwhile, Ashes of the Abhorrent quietly pads your life total every time a creature bites the dust, completely offsetting the life payments required to keep Yawgmoth's sacrifice loop firing indefinitely.
