Zask, Skittering Swarmlord + Verdant Succession + Viscera Seer

Zask, Skittering Swarmlord

Verdant Succession

Viscera Seer

How it works

1. Activate Viscera Seer 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 Viscera Seer ability.
6. Repeat.
