This intricate engine turns the humble top of your library into an endless workshop, fueled entirely by the clever synergy between Mm'menon, the Right Hand and Sensei's Divining Top. While Sensei's Divining Top constantly rediscovers itself on top of your library for a single mana, Mm'menon, the Right Hand grants you both the permission to cast it from there and a mana-producing ability that satisfies its cost. Every time you cast it, Sai, Master Thopterist swoops in to manufacture a fresh 1/1 Thopter artifact creature token, which in turn taps for the exact blue mana needed to keep the loop going thanks to Mm'menon, the Right Hand's text. Meanwhile, Rising of the Day ensures your new mechanical swarm arrives with haste, though the Thopters will spend their energy resting back into a tapped state immediately to pay for the continuous ritual.
