Sensei's Divining Top + Displacer Kitten + Narset, Parter of Veils + Foundry Inspector

Sensei's Divining Top

Displacer Kitten

Narset, Parter of Veils

Foundry Inspector

How it works

1. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Activate Narset by removing two loyalty counters from it, causing you to look at the top four cards of your library, then reveal Sensei's Divining Top and put it into your hand.
3. Cast Sensei's Divining Top by paying 0
4. Displacer Kitten triggers, blinking Narset.
5. Repeat.

This loop transforms Sensei's Divining Top into an infinite engine by leveraging Foundry Inspector to reduce its mana cost to zero, allowing you to cast it repeatedly for free. Every time you cast the artifact, Displacer Kitten triggers its Avoidance ability to blink Narset, Parter of Veils, resetting her loyalty counters so you can immediately use her −2 ability to tutor the top right back to your hand. Meanwhile, Narset's static ability ensures your opponents are locked out of drawing extra cards while you cycle through your deck.
