Sensei's Divining Top + Semblance Anvil + Fateful Discovery

Sensei's Divining Top

Semblance Anvil

Fateful Discovery

How it works

1. Cast Sensei's Divining Top by paying 0 due to Semblance Anvil.
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 engine uses Semblance Anvil to reduce the cost of Sensei's Divining Top down to zero, allowing you to cast the artifact for free as often as you like. Every time Sensei's Divining Top enters the battlefield, Fateful Discovery triggers to net you a card, but responding to that trigger by tapping the top puts it right back on top of your library to be drawn. By looping this sequence endlessly, you generate infinite card draw, infinite draw triggers, and a near-infinite storm count.
