Vorapede

How it works

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