Woe Strider

Sightless Ghoul

How it works

1. Activate Woe Strider by sacrificing Sightless Ghoul
2. When Sightless Ghoul dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
3. Activate Woe Strider by sacrificing Sightless Ghoul
4. When Sightless Ghoul dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
5. Resolve both Woe Strider abilities from step 1 and 3.
6. Repeat.
