This clever loop takes advantage of Time Sieve's ability to turn a hoard of artifacts into infinite extra turns, fueled entirely by the automation of Myr Turbine. Each cycle, Myr Turbine's second ability trades a squad of five Myr—including the four fresh tokens gifted the moment Myr Battlesphere enters the battlefield—to tutor up that very same massive mechanical threat straight from your library. Once Time Sieve gobbles up those five artifacts to buy you another full rotation, Hoverstone Pilgrim steps in to pay its modest two-mana activation fee and tuck the fallen Myr Battlesphere safely back onto the bottom of your library, right where Myr Turbine can find it again.
