Strength of Will + Walking Ballista + Doubling Season

Strength of Will

Walking Ballista

Doubling Season

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 Doubling Season.
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 loop turns Walking Ballista into a self-sustaining engine of destruction by using Strength of Will to shield it from its own self-inflicted damage while enabling explosive growth. Each time Walking Ballista pings itself, the damage it takes triggers its new triggered ability to gain counters, which Doubling Season then amplifies by doubling every counter placed upon it. This exponential growth generates a surplus of counters that can be freely peeled off to deal infinite damage to any target while retaining a lethal amount to finish the game.
