Zask, Skittering Swarmlord + Verdant Succession + Carrion Feeder

Zask, Skittering Swarmlord

Verdant Succession

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing another nontoken green Insect.
2. When the Insect dies, Zask and Verdant Succession trigger.
3. Resolve the Zask trigger, putting the Insect on the bottom of your library from your graveyard and causing you to mill two cards.
4. Resolve the Verdant Succession trigger, searching your library for that Insect and putting it onto the battlefield.
5. Resolve the Carrion Feeder ability.
6. Repeat.

By sacrificing a green nontoken Insect to Carrion Feeder, you trigger a clever loop that lets you continuously recycle your creatures while growing your sacrifice threat. Zask, Skittering Swarmlord intercepts the death to tuck the Insect away and mill two cards into your graveyard, while Verdant Succession capitalizes on the same death to instantly tutor a fresh copy of that exact creature straight onto the battlefield. Because Zask also lets you play lands and cast Insect spells directly from your graveyard, this engine feeds itself endlessly to generate staggering amounts of death triggers and counter growth.
