Gatta and Luzzu + Lae'zel, Vlaakith's Champion + Walking Ballista

Gatta and Luzzu

Lae'zel, Vlaakith's Champion

Walking Ballista

How it works

1. Cast Gatta and Luzzu either from your hand or from the command zone by paying 2 plus commander tax, if applicable.
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 Lae'zel.
4. Activate Walking Ballista by removing a +1/+1 counter from it, dealing 1 damage to any target.
5. Repeat from step 3.
