Sensei's Divining Top + Herald of Kozilek + Fateful Discovery

Sensei's Divining Top

Herald of Kozilek

Fateful Discovery

How it works

1. Cast Sensei's Divining Top by paying 0 due to Herald of Kozilek.
2. When Sensei's Divining Top enters, Fateful Discovery triggers.
3. Holding priority, 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.
4. Resolve the Fateful Discovery trigger, causing you to draw Sensei's Divining Top from your library
5. Repeat

This ingenious loop transforms Sensei's Divining Top into a self-sustaining engine by leaning on a clever stack trick. First, Herald of Kozilek provides the crucial cost reduction that lets you cast the Top for free, while Fateful Discovery acts as your payoff, turning every entry of the artifact into a fresh card drawn. When you tap the Top in response to its own entry trigger to put it on top of your library, Fateful Discovery resolves to draw it right back out into your hand, ready to be recast for zero mana.
