Mite Overseer + Ashnod's Altar + Verdant Sun's Avatar + Stridehangar Automaton

Mite Overseer

Ashnod's Altar

Verdant Sun's Avatar

Stridehangar Automaton

How it works

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

This ingenious loop relies on Mite Overseer's ability to pump out tokens, which is supercharged by Stridehangar Automaton's replacement effect to double your production into a steady stream of artifact creatures. Each time these tokens hit the battlefield, Verdant Sun's Avatar swoops in to reward your growing army with a steady stream of life gain. Finally, Ashnod's Altar converts those freshly minted tokens into a surplus of colorless mana, which then feeds right back into paying for Mite Overseer's activation cost to keep the cycle spinning infinitely.
