Activate Mite Overseer by paying 3W/P, creating two creature tokens.
When the creature tokens enter the battlefield, Hinterland Sanctifier triggers twice, causing you to gain 2 life.
Activate Ashnod's Altar twice by sacrificing the creature tokens, adding CCCC.
Repeat.
This clever loop relies on Stridehangar Automaton's replacement effect to turn a single token generation event into a two-for-one deal, allowing Mite Overseer to flood your board with artifacts whenever its ability is activated. Ashnod's Altar converts those newly minted bodies straight back into colorless mana, feeding the very engine that created them while generating a massive surplus. Meanwhile, Hinterland Sanctifier quietly tracks the chaos, turning every single entry into a steady stream of life to easily offset any health paid for the Overseer's hybrid mana cost.
