Walking Ballista

Sunbond

How it works

1. Give Walking Ballista lifelink.
2. Activate Walking Ballista's second ability by removing a +1/+1 counter from it, dealing 1 damage to any target and causing you to gain 1 life.
3. Walking Ballista triggers, putting a +1/+1 counter on itself.
4. Repeat from step 2.
