This clever loop turns a modest artifact into a relentless engine of destruction by leaning entirely on cost reduction and clever timing. With Longshot, Rebel Bowman on the board, Sensei's Divining Top becomes completely free to cast, while also triggering Longshot to continuously blast your opponents for damage. As the Top re-enters, Fateful Discovery instantly rewards the artifact's arrival by forcing a draw. By tapping Sensei's Divining Top in response to that draw trigger—putting the Top safely back on top of your library just in time for Fateful Discovery to draw it right back out—you establish a perpetual motion machine that endlessly cycles the artifact for infinite card draws and near-infinite damage.
