Sensei's Divining Top + Urza, Lord Protector + Fateful Discovery

Sensei's Divining Top

Urza, Lord Protector

Fateful Discovery

How it works

1. Cast Sensei's Divining Top by paying 0 due to Urza.
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 charming loop transforms a humble library manipulator into an endless engine by leveraging Urza, Lord Protector to make Sensei's Divining Top completely free to cast. With that cost reduction in place, every time you cast the artifact, Fateful Discovery rewards your efforts by triggering a card draw. You then float the Top right back onto your library in response, letting Fateful Discovery pluck it right back out into your hand to repeat the cycle infinitely.
