You may play lands and cast Insect spells from your graveyard.
Whenever another Insect you control dies, put it on the bottom of its owner's library, then mill two cards. (Put the top two cards of your library into your graveyard.)
: Target Insect gets +1/+0 and gains deathtouch until end of turn. ( can be paid with either or .)
Build a wide, recursive Insect board that grinds value off the graveyard, then turn sideways with deathtouch-pumped attackers or go infinite with sacrifice loops. Early turns ramp and self-mill to stock the yard, mid-game you flood the board with Insect tokens and creatures, and Zask lets you replay milled lands and recast dead Insects for relentless pressure.
Built-in card advantage and recursion—dead Insects loop back and refill your library while milling fuels graveyard synergies
Cheap repeatable deathtouch pump turns any small Insect into a removal threat and makes attacks miserable to block
Resilient to board wipes since lands and Insects come back from the graveyard
Strong sacrifice/aristocrats engine with a deep, self-replacing creature base
Free sacrifice outlet that combos with recurring Insects and token generators for mana and triggers.
Add fast mana and ramp (Sol Ring, Arcane Signet, Sakura-Tribe Elder) to deploy Zask ahead of schedule, then tighten the aristocrats package with Blood Artist, Zulaport Cutthroat, and free sacrifice outlets like Phyrexian Altar to enable drain loops. Include targeted graveyard protection and your own hate pieces, and lean into efficient token producers plus Skullclamp to convert the recursive swarm into nonstop cards and an inevitable win.
