Mite Overseer + Ashnod's Altar + Chatterfang, Squirrel General + Lifecreed Duo

Mite Overseer

Ashnod's Altar

Chatterfang, Squirrel General

Lifecreed Duo

How it works

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

This clever loop turns Mite Overseer's Phyrexian Mite activation into a self-sustaining engine by taking advantage of Chatterfang, Squirrel General's replacement effect to double every token creation into both a Mite and a Squirrel. With Ashnod's Altar providing more than enough colorless mana to continuously fund the Mite Overseer ability upon sacrificing those newly generated creatures, you create a surplus of energy alongside endless sacrifices. Meanwhile, Lifecreed Duo quietly sits back and capitalizes on every single entry to buffer your life total indefinitely.
