This loop is a masterclass in recycling your topdeck, fueled entirely by the synergy between Mm'menon, the Right Hand and Sensei's Divining Top. By using Sensei's Divining Top's tap ability to draw a card while tucking itself back onto your library, Mm'menon, the Right Hand steps in to let you recast that very same artifact from the top of your library. Each time you cast it, Sai, Master Thopterist rewards your efforts by churning out a 1/1 Thopter token, which can immediately tap for blue mana thanks to Mm'menon, the Right Hand's static mana ability to pay for the Top's casting cost. Meanwhile, Akroma's Memorial sits proudly on the battlefield, granting your swarm of newly minted Thopters a terrifying suite of evergreen keywords like flying, haste, and vigilance the moment they arrive.
