Walking Ballista + Unspeakable Symbol + Taii Wakeen, Perfect Shot

Walking Ballista

Unspeakable Symbol

Taii Wakeen, Perfect Shot

How it works

1. Activate Taii Wakeen by paying at least 2 and tapping it.
2. Give Walking Ballista lifelink, if needed.
3. If Walking Ballista has less than two +1/+1 counters on it, activate Unspeakable Symbol by paying 3 life, putting a +1/+1 counter on Walking Ballista.
4. Activate Walking Ballista's second ability by removing a +1/+1 counter from it, dealing at least 3 damage to an opponent or a permanent an opponent controls, and causing you to gain at least 3 life.
5. Repeat from step 3.
