Viscera Seer + Thran Vigil + Safehold Elite

Viscera Seer

Thran Vigil

Safehold Elite

How it works

1. Activate Viscera Seer by sacrificing Safehold Elite.
2. When Safehold Elite dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. Thran Vigil triggers, putting a +1/+1 counter on Safehold Elite.
4. Resolve the Viscera Seer ability.
5. Repeat.
