The Fourth Doctor + Displacer Kitten + Sensei's Divining Top + Etherium Sculptor

The Fourth Doctor

Displacer Kitten

Sensei's Divining Top

Etherium Sculptor

How it works

1. Cast Sensei's Divining Top either from your hand or from the top of your library by paying 0.
2. Displacer Kitten triggers, and The Fourth Doctor triggers if you had cast Sensei's Divining Top from your library.
3. Resolve the Displacer Kitten trigger, blinking The Fourth Doctor.
4. Resolve the Fourth Doctor trigger, if applicable, creating a Food token.
5. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top onto the top of your library.
6. Repeat.

This ingenious loop relies on Sensei's Divining Top being cast for free as a historic artifact spell thanks to Etherium Sculptor's cost reduction and The Fourth Doctor's ability to play historic spells directly from the top of your library. Each time you cast the Top, Displacer Kitten triggers to blink The Fourth Doctor—letting you generate a steady stream of Food tokens—while the Top itself taps to draw a card and safely return to the very top of your library. Because the Top costs nothing to recast and effortlessly replaces itself in your hand, you can repeat this process indefinitely to draw your entire deck, flood the board with triggers, and churn out an endless supply of artifacts.
