Melira, Sylvok Outcast + Woe Strider + Twilight Shepherd

Melira, Sylvok Outcast

Woe Strider

Twilight Shepherd

How it works

1. Activate Woe Strider by sacrificing Twilight Shepherd.
2. When Twilight Shepherd 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 elegant loop centers on Twilight Shepherd and its persist ability, which normally would exhaust itself after a single recursion due to the accumulation of a -1/-1 counter. Melira, Sylvok Outcast completely bypasses this limitation with her static ability, preventing -1/-1 counters from ever being placed on your creatures and allowing the Shepherd to enter the battlefield pristine every single time it returns. Meanwhile, Woe Strider provides the necessary sacrifice outlet to trigger the loop at will, turning the repeated death and rebirth into an engine for infinite enter-the-battlefield triggers, death triggers, and perpetual scry 1 manipulation.
