Sensei's Divining Top + Helm of Awakening + The Reality Chip

Sensei's Divining Top

Helm of Awakening

The Reality Chip

How it works

1. Activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Cast Sensei's Divining Top from the top of your library by paying 0.
3. Repeat

This delightful loop turns your library into your hand by exploiting a clever cost reduction and a clever top-deck manipulation. With Helm of Awakening on the battlefield reducing costs by {1}, Sensei's Divining Top becomes completely free to recast once you tap it to draw a card and place it on top of your library. The Reality Chip ensures you can cast that top right back off your library immediately, letting you tap, draw, and recast the Top on an endless loop.
