This engine relies on turning your creature swarm into a self-sustaining mana loop, starting with the mana-generating ability granted by Cryptolith Rite to tap your newly born creatures the moment they arrive. Fires of Yavimaya provides the crucial haste they need to tap immediately without waiting around for summoning sickness, ensuring the cycle can begin on the spot. Ant Queen acts as the primary engine by turning that mana right back into fresh bodies, while Chatterfang, Squirrel General dramatically doubles your output by generating a matching army of Squirrels alongside every Insect, easily funding the activation costs and keeping the loop infinitely rolling.
