This clever loop turns your topdeck into an endless engine, fueled by Mm'menon, the Right Hand granting your artifacts a special mana ability that pays for spells cast from anywhere other than your hand. By tapping Sensei's Divining Top to draw a card and place itself back on your library, you set up the very top of your library for Mm'menon's permission to cast artifact spells directly from it. Enthusiastic Mechanaut steps in to reduce that casting cost to zero, allowing you to replay Sensei's Divining Top for free and repeat the process indefinitely for boundless card draw and an insurmountable storm count.
