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}.)

Trample When this creature dies, exile it, then return two creature cards at random from your graveyard to the battlefield.

Whenever a green nontoken creature dies, that creature's controller may search their library for a card with the same name as that creature, put it onto the battlefield, then shuffle.

Destroy target creature. If that creature dies this way, its controller creates two tokens that are copies of that creature, except their power is half that creature's power and their toughness is half that creature's toughness. Round up each time.
