Zask, Skittering Swarmlord + Aluren + Viscera Seer

Zask, Skittering Swarmlord

Aluren

Viscera Seer

How it works

1. Cast the Insect from your hand or graveyard by paying 0 due to Aluren.
2. Activate Viscera Seer by sacrificing the Insect.
3. When the Insect dies, Zask triggers.
4. Holding priority, cast the Insect from your graveyard by paying 0 due to Aluren.
5. Resolve the Zask ability, causing you to mill two cards.
6. Resolve the Viscera Seer ability.
7. Repeat from step 2.

This delightfully insidious loop lets you churn through your entire library for zero mana by exploiting the unrestricted freedom of Aluren. Whenever you sacrifice your chosen creature to Viscera Seer's ability, Zask, Skittering Swarmlord steps in to recycle the fallen bug back toward your library while feeding you a steady stream of self-mill. Because Zask also grants the vital ability to cast Insect spells directly from your graveyard, Aluren's passive cost-reduction allows you to immediately replay your sacrificial fodder for free before the graveyard trigger even resolves. It’s an endless, self-sustaining engine of sacrifice triggers, scrys, and storm count that easily overwhelms your opponents.
