Falco Spara, Pactweaver

Sensei's Divining Top

Shabraz, the Skyshark

Starnheim Courser

How it works

1. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Shabraz triggers, putting a +1/+1 counter on it and causing you to gain 1 life.
3. Cast Sensei's Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
4. Repeat.

This engine transforms a simple artifact into an endless, self-sustaining loop by turning your library's top card into a hidden hand. Sensei's Divining Top naturally replaces itself by drawing a card and resting on top of your library, but Starnheim Courser reduces its mana cost to zero, allowing you to bypass the usual cost entirely. Meanwhile, Falco Spara, Pactweaver provides the vital alternate casting permission and resource, letting you replay the Top by simply removing a counter from one of your creatures instead of paying mana. Every single iteration of this cycle triggers Shabraz, the Skyshark, which scales into a massive threat while padding your life total with every card drawn.
