Urza, Lord Protector cuts the cost of artifacts and spells by 1, making Sensei's Divining Top free to cast; every cast triggers Displacer Kitten, which blinks The One Ring, resetting its burden counters and keeping it from becoming a liability. The Top's draw-and-return ability feeds itself back off The One Ring's tap, closing the loop indefinitely.

Recipe

How it works

Prerequisites

—

Steps

Cast Sensei's Divining Top by paying .
Displacer Kitten triggers, blinking The One Ring.
Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top from the battlefield onto the top of your library.
Activate The One Ring by tapping it, putting a burden counter on it and causing you to draw Sensei's Divining Top from your library.
Repeat.

Result

Infinite card draw; Infinite draw triggers; Near-infinite storm count

Variations

Cheaper, tighter, alternate lines

Sensei's Divining Top is the only piece with a clean substitute — Cloud Key or Semblance Anvil can replicate the cost reduction if Urza is removed, though both require more setup. Once the library is drawn, the near-infinite storm count pairs naturally with Aetherflux Reservoir as the kill; Thassa's Oracle is the backup closer if storm is unavailable.
