Sensei's Divining Top + Armor Wars + Fateful Discovery

Sensei's Divining Top

Armor Wars

Fateful Discovery

How it works

1. Cast Sensei's Divining Top by paying 0 due to Armor Wars.
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 cunning loop turns a humble spinning top into a ceaseless engine of discovery. With Armor Wars reducing artifact spell costs down to zero, casting Sensei's Divining Top becomes entirely free, instantly triggering Fateful Discovery to ready your hand. Before that draw resolves, you tap the Top to draw a card and slide it right back onto your library, perfectly positioning it to be plucked out by the very trigger it just created.
