Grist, Voracious Larva // Grist, the Plague Swarm

Deathtouch Whenever Grist or another creature you control enters, if it entered from your graveyard or you cast it from your graveyard, you may pay {G}. If you do, exile Grist, then return it to the battlefield transformed under its owner's control. +1: Create a 1/1 black and green Insect creature token, then mill two cards. Put a deathtouch counter on the token if a black card was milled this way. −2: Destroy target artifact or enchantment. −6: For each creature card in your graveyard, create a token that's a copy of it, except it's a 1/1 black and green Insect.
