Gatta and Luzzu + Walking Ballista + Doc Samson, Super Psychiatrist

Gatta and Luzzu

Walking Ballista

Doc Samson, Super Psychiatrist

How it works

1. Cast Gatta and Luzzu by paying 2.
2. When Gatta and Luzzu enters the battlefield, it triggers, targeting Walking Ballista.
3. Activate Walking Ballista by removing a +1/+1 counter from it, targeting itself, but instead putting two +1/+1 counters on it due to Gatta and Luzzu and Doc Samson.
4. Activate Walking Ballista by removing a +1/+1 counter from it, dealing 1 damage to any target.
5. Repeat from step 3.

This loop turns Walking Ballista into a self-sustaining engine of growth and destruction by weaponizing its own self-inflicted damage. When you cast Gatta and Luzzu with flash, its entry trigger targets Walking Ballista to redirect and convert any damage dealt to it into prevention and corresponding +1/+1 counters. Meanwhile, Doc Samson, Super Psychiatrist amplifies those gains by slipping an extra counter onto the permanent every time counters are placed. By removing a counter to ping Walking Ballista for 1 damage, Gatta and Luzzu prevents that damage and triggers a net gain of counters thanks to Doc Samson, leaving you free to filter the excess counters into infinite damage for any target.
