Vigor + Triskelion + Doc Samson, Super Psychiatrist

Vigor

Triskelion

Doc Samson, Super Psychiatrist

How it works

1. Activate Triskelion by removing a +1/+1 counter on it, targeting itself, but putting two +1/+1 counters on it due to Vigor.
2. Activate Triskelion by removing a +1/+1 counter on it, dealing 1 damage to any target.
3. Repeat.

This loop relies on a brilliant synergy of replacement effects to turn Triskelion into a self-sustaining engine. Ordinarily, pinging its own body would shrink its power, but Vigor steps in to convert that self-inflicted damage into prevention, granting +1/+1 counters instead. Meanwhile, Doc Samson, Super Psychiatrist supercharges this growth by ensuring that every counter placed on Triskelion is amplified, allowing it to rapidly outpace its own ammunition costs and yield infinite damage and infinite +1/+1 counters.
