Displacer Kitten + The One Ring + Sensei's Divining Top + Gran-Gran

Displacer Kitten

The One Ring

Sensei's Divining Top

Gran-Gran

How it works

1. Cast Sensei's Divining Top by paying 0.
2. Displacer Kitten triggers, blinking The One Ring.
3. 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.
4. 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.
5. Repeat.

This ingenious loop spins up infinite card draw by turning Sensei's Divining Top into a self-replenishing engine right off the top of your library. The magic relies on Displacer Kitten's avoidance trigger, which uses each cast of Sensei's Divining Top to blink The One Ring, resetting its protection and clearing away its dangerous burden counters before they can drain your life. Meanwhile, Gran-Gran's passive cost reduction makes casting Sensei's Divining Top completely free while quietly churning through your deck with her loot trigger whenever she taps.
