Melira, Sylvok Outcast + Woe Strider + Gravelgill Axeshark

Melira, Sylvok Outcast

Woe Strider

Gravelgill Axeshark

How it works

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

This clever sacrifice loop relies on Gravelgill Axeshark and its persist ability to continuously cycle in and out of the graveyard. Ordinarily, persist would saddle the creature with a -1/-1 counter upon return, stopping the loop in its tracks, but Melira, Sylvok Outcast steps in with her static ability to completely prevent those -1/-1 counters from ever being placed. With that impediment removed, Woe Strider acts as the engine, letting you repeatedly sacrifice the Axeshark to trigger an endless stream of enters-the-battlefield, leaves-the-battlefield, and death events while filtering your library with infinite scry 1 triggers.
