Sensei's Divining Top + Herald of Kozilek + The Reality Chip

Sensei's Divining Top

Herald of Kozilek

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 elegant engine turns a modest artifact into a self-sustaining draw-and-storm loop by leveraging cost reduction and top-deck casting. While The Reality Chip grants you the crucial ability to cast spells directly from the top of your library, Herald of Kozilek provides the essential discount that reduces Sensei's Divining Top's mana cost down to zero. You simply tap Sensei's Divining Top to draw a card and place it on top of your library, then cast it back out for free, repeating the cycle as many times as you desire.
