Mite Overseer + Ashnod's Altar + Trostani, Selesnya's Voice + Chatterfang, Squirrel General

Mite Overseer

Ashnod's Altar

Trostani, Selesnya's Voice

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

This intricate loop relies on Mite Overseer as both the spark and the engine, using its activated ability to pump out Phyrexian Mite tokens. Chatterfang, Squirrel General doubles your token output, turning every single activation into a swarm of both Mites and Squirrels while feeding your death-trigger needs. Meanwhile, Trostani, Selesnya's Voice watches over the chaos, converting each new arrival into a steady stream of lifegain, and Ashnod's Altar promptly sacrifices the fresh tokens for the colorless mana needed to pay for the Overseer's ability all over again.
