As long as Grist isn't on the battlefield, it's a 1/1 Insect creature in addition to its other types. +1: Create a 1/1 black and green Insect creature token, then mill a card. If an Insect card was milled this way, put a loyalty counter on Grist and repeat this process. −2: You may sacrifice a creature. When you do, destroy target creature or planeswalker. −5: Each opponent loses life equal to the number of creature cards in your graveyard.

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.) {1}{B/G}: Target Insect gets +1/+0 and gains deathtouch until end of turn. ({B/G} can be paid with either {B} or {G}.)

Equipped creature gets +1/-1. Whenever equipped creature dies, draw two cards. Equip {1}

Flying, deathtouch When this creature enters, create four 1/1 green Insect creature tokens with flying and deathtouch.

This land enters tapped unless you control a Swamp or a Forest. {T}: Add {B} or {G}.

Landfall — Whenever a land you control enters, create a 1/1 green Insect creature token. If you control six or more lands, create a token that's a copy of this creature instead.

Search your library for up to two basic land cards, reveal those cards, put one onto the battlefield tapped and the other into your hand, then shuffle.
