The Fourth Doctor + Displacer Kitten + Sensei's Divining Top + Sami, Wildcat Captain

The Fourth Doctor

Displacer Kitten

Sensei's Divining Top

Sami, Wildcat Captain

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 intricate engine turns the humble top of your library into an endless card-drawing machine by looping Sensei's Divining Top entirely for free. The Fourth Doctor makes this possible by letting you look at the top of your library and casting Sensei's Divining Top right back off it once each turn—wait, actually, every time you redraw it! Meanwhile, Sami, Wildcat Captain provides crucial cost reduction via affinity for artifacts, while Displacer Kitten blinks The Fourth Doctor whenever you cast your noncreature artifact, generating a steady stream of Food tokens and resetting any triggered abilities along the way.
