Strength of Will + Walking Ballista + Winding Constrictor

Strength of Will

Walking Ballista

Winding Constrictor

How it works

1. Cast Strength of Will by paying 1, targeting Walking Ballista.
2. Activate Walking Ballista by removing a +1/+1 counter from it, dealing 1 damage to it.
3. Walking Ballista triggers, putting two +1/+1 counters on it due to Winding Constrictor.
4. Activate Walking Ballista by removing a +1/+1 counter from it, dealing 1 damage to any target.
5. Repeat from step 2.

This clever sequence turns Walking Ballista into a self-sustaining engine of destruction by turning its own damage into growth. It all begins when you cast Strength of Will targeting the Ballista, granting it temporary indestructible and a vital trigger whenever it takes damage. Because Winding Constrictor oversees the board, any counters placed on your creatures are multiplied—meaning the damage dealt to Walking Ballista by its own ability doesn't just bounce off its indestructible frame, but actually yields a net gain of counters. With this surplus, you can continuously remove a counter to ping the Ballista for self-harm to fuel the loop, and then redirect subsequent activations to deal infinite damage to any target.
