Melira, Sylvok Outcast + Blasting Station + Rendclaw Trow

Melira, Sylvok Outcast

Blasting Station

Rendclaw Trow

How it works

1. Activate Blasting Station by tapping it and sacrificing Rendclaw Trow.
2. When Rendclaw Trow dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Melira.
3. When Rendclaw Trow enters, Blasting Station triggers, untapping Blasting Station
4. Resolve the Blasting Station ability from step 1
5. Repeat.

This loop turns an ordinary scarecraw into an endless artillery shell by exploiting the interaction between death and counters. When you sacrifice Rendclaw Trow to Blasting Station, its persist ability normally brings it back with a hindering -1/-1 counter; however, Melira, Sylvok Outcast's static ability prevents those counters from ever being placed on your creatures. Because Rendclaw Trow re-enters the battlefield completely pristine, Blasting Station's triggered ability gladly untaps itself upon the creature's arrival, allowing you to repeat the devastating cycle for infinite damage.
