Vigor + Walking Ballista + Dictate of the Twin Gods

Vigor

Walking Ballista

Dictate of the Twin Gods

How it works

1. Activate Walking Ballista's second ability by removing a +1/+1 counter from it, putting two +1/+1 counters on it due to Vigor.
2. Activate Walking Ballista's second ability by removing a +1/+1 counter from it, dealing 2 damage to any target.
3. Repeat as desired.

This delightful loop turns Walking Ballista into a self-sustaining engine by letting its own gunfire fuel its growth. Because Vigor redirects damage dealt to your creatures into prevention and counter growth, and Dictate of the Twin Gods steps in to double that output, every single ping fired off generates more counters than it consumes. You can effortlessly cycle through this sequence to pump out an unbounded number of +1/+1 counters and deal infinite damage to any target you choose.
