Tarrian's Soulcleaver + Scurry Oak + Woe Strider

Tarrian's Soulcleaver

Scurry Oak

Woe Strider

How it works

1. Put a +1/+1 counter on Scurry Oak.
2. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
3. Activate Woe Strider by sacrificing the Squirrel.
4. When the Squirrel dies, Tarrian's Soulcleaver triggers, putting a +1/+1 counter on Scurry Oak.
5. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
6. Resolve the Woe Strider ability, causing you to scry 1.
7. Repeat from step 3.

This loop relies on a brilliant feedback loop between Scurry Oak's counter-triggered token generation and the graveyard utility of Woe Strider. By sacrificing the Squirrel token produced by Scurry Oak to Woe Strider, you send a creature to the graveyard, which immediately triggers Tarrian's Soulcleaver to place a brand-new +1/+1 counter back onto Scurry Oak. That counter addition restarts Scurry Oak's own trigger, spawning another Squirrel to feed back into Woe Strider for endless sacrifices, scry triggers, and scaling power.
