Sensei's Divining Top + Starnheim Courser + Fateful Discovery

Sensei's Divining Top

Starnheim Courser

Fateful Discovery

How it works

1. Cast Sensei's Divining Top by paying 0 due to Starnheim Courser.
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 clever little loop turns your library into your hand by stacking triggers and continuous cost reduction in your favor. With Starnheim Courser holding down the fort by making artifact spells completely free, you can cast Sensei's Divining Top for the bargain price of zero mana. The moment it hits the board, Fateful Discovery triggers to reward that artifact entry with a fresh card draw, but you can respond by tapping the Top to draw a card and tuck it safely back onto the top of your library. When that Fateful Discovery trigger finally resolves, you'll draw the very same Sensei's Divining Top right back into your hand, ready to cast it all over again for an endless cascade of draws and storm count.
