This cunning interaction transforms Walking Ballista into an infinite damage and growth engine by weaponizing damage against itself. Because Gatta and Luzzu prevents any damage dealt to the chosen creature and replaces it with an equal number of +1/+1 counters, removing a counter to ping the Ballista doesn't harm it—it triggers a growth event instead. That's where Loading Zone shines as the amplifier, doubling those replacement counters so that every activation nets a surplus (+1/+1 counter) rather than breaking even. The result is an explosive loop that infinitely grows your creatures and incinerates any target in your path.
