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

Mite Overseer

Ashnod's Altar

Soul's Attendant

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's Attendant triggers twice, causing you to gain 2 life.
3. Activate Ashnod's Altar twice by sacrificing the creature tokens, adding CCCC.
4. Repeat.

This engine spins into motion by leveraging Mite Overseer's activated ability to continuously pump out token pairs, a process heavily subsidized and doubled by Chatterfang, Squirrel General's replacement effect. Every time those tokens flood the battlefield, Soul's Attendant dutifully rewards you with a steady stream of life, ensuring your health total remains healthy while you churn through the loop. Finally, Ashnod's Altar steps in to harvest those newly minted tokens for raw colorless mana, yielding more than enough energy to pay for the Overseer's activation cost again and keep the cycle spinning infinitely.
