Vizier of Remedies + Woe Strider + Grazing Kelpie

Vizier of Remedies

Woe Strider

Grazing Kelpie

How it works

1. Activate Woe Strider by sacrificing Grazing Kelpie.
2. When Grazing Kelpie dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Vizier of Remedies.
3. Resolve the Woe Strider ability
4. Repeat.

This elegant loop relies on the interaction between Grazing Kelpie and Vizier of Remedies to completely bypass the intended downside of persist. Because Vizier of Remedies reduces the -1/-1 counter from persist to zero, Grazing Kelpie can return to the battlefield fresh every time Woe Strider sacrifices it to the graveyard. Woe Strider not only acts as the sacrifice outlet to keep the engine running, but also lets you filter your entire library using its scry ability with every single iteration.
