Woe Strider + Safehold Elite + Hardened Academic

Woe Strider

Safehold Elite

Hardened Academic

How it works

1. Activate Woe Strider 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. Hardened Academic triggers, putting a +1/+1 counter on Safehold Elite.
4. Resolve the Woe Strider ability.
5. Repeat.
