Vigor + Triskelion + Branching Evolution

Vigor

Triskelion

Branching Evolution

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 ingenious loop turns Triskelion into a self-sustaining engine of destruction by leveraging the damage-redirection of Vigor. Every time Triskelion removes a counter to shoot itself, Vigor steps in to prevent that damage and instead grows the creature, a multiplier further amplified by the doubling effect of Branching Evolution. Because Triskelion can repeatedly target itself and still net extra counters through these replacement effects, you can generate unbounded power and endless damage to close out the game.
