Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Woe Strider

Nardole, Resourceful Cyborg

How it works

1. Activate Woe Strider by sacrificing Nardole
2. When Nardole 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 Nardole
4. When Nardole 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.
