Vigor + Triskelion + Hardened Scales

Vigor

Triskelion

Hardened Scales

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 delightfully self-contained loop turns Triskelion into a lethal engine by weaponizing its own self-inflicted damage. Because Vigor redirects that damage into a protective growth spurt, every counter you strip away comes back with interest, a return on investment further amplified by Hardened Scales adding an extra counter to the pile each time. By cycling this process, you can continually feed Triskelion's ability to deal infinite damage to any target while simultaneously growing every creature you control to arbitrarily large proportions.
