This clever loop turns the unassuming Sensei's Divining Top into an infinite card-drawing engine by leveraging cost reduction and enter-the-battlefield triggers. Lyse Hext does the heavy lifting of slashing the Top's mana cost down to zero while also boosting its own power and granting double strike via prowess whenever you cast it. Meanwhile, Fateful Discovery watches over the proceedings, converting every single re-entry of the Top into a fresh card draw. By responding to Fateful Discovery's trigger with the Top's own tapping ability, you seamlessly slide Sensei's Divining Top back onto your library just in time to draw it right back out again, fueling an explosive storm count and an overwhelmingly large attacker.
