Foundry Inspector reduces Sensei's Divining Top to zero mana, so each cast triggers Displacer Kitten, which blinks The One Ring to reset its burden counters and give it haste again. Top's second ability puts it back on the library, The One Ring draws it, and the loop repeats at no additional cost. Any blue artifact shell — Urza, Lord High Artificer, Emry, Lurker of the Loch, or Malcolm, Alluring Scoundrel — can assemble this with the tutors those commanders already want.

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

Cheaper, tighter, alternate lines

Replace Foundry Inspector with Etherium Sculptor or Helm of Awakening if the Inspector slot is contested — any cost reducer that makes Top free completes the loop. The engine draws the whole library but doesn't close by itself; pair it with Thassa's Oracle or Aetherflux Reservoir, both of which blue artifact decks already run as standalone win conditions.
