Mite Overseer + Ashnod's Altar + Soul Warden + Chatterfang, Squirrel General

Mite Overseer

Ashnod's Altar

Soul Warden

Chatterfang, Squirrel General

How it works

1. Activate Mite Overseer by paying 3W/P, creating two creature tokens.
2. When the creature tokens enter the battlefield, Soul Warden triggers twice, causing you to gain 2 life.
3. Activate Ashnod's Altar twice by sacrificing the creature tokens, adding CCCC.
4. Repeat.

This loop is a masterclass in token multiplication, turning Mite Overseer's activated ability into an infinite resource engine. By paying into the Overseer, Chatterfang, Squirrel General steps in to double your output, instantly spawning both a Phyrexian Mite and a Squirrel token for every single activation. Soul Warden watches over the carnage, turning every double-entry into a steady stream of life, while Ashnod's Altar readily consumes your newly minted army to generate more than enough colorless mana to keep the cycle spinning indefinitely.
