This clever loop is centered around Mite Overseer’s activated ability, which feeds your engine by producing tokens for a bargain. The magic truly happens because Quina, Qu Gourmet amplifies every single creation event by throwing an extra Frog into the mix, swelling your board with two distinct bodies for the price of one. Ashnod's Altar then happily converts those sacrificial offerings into a surplus of colorless mana, more than enough to continually pay for the Overseer's activation costs with mana to spare. Meanwhile, Leyline of Vitality rests quietly on the battlefield to harvest life-gain triggers from every incoming arrival, cushioning your life total against any life-payment costs required along the way.
