Falco Spara, Pactweaver + Sensei's Divining Top + Shabraz, the Skyshark + Cloud Key

Falco Spara, Pactweaver

Sensei's Divining Top

Shabraz, the Skyshark

Cloud Key

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 ingenious loop lets you draw your entire deck by repeatedly casting and cycling Sensei's Divining Top from the very top of your library. The engine is made possible by Falco Spara, Pactweaver, whose static ability lets you cast spells from the top of your library by trading a counter from a creature instead of paying mana, a cost reduction neatly offset by Cloud Key naming "artifact" to make the Top free to cast. As you constantly redraw and replay your artifacts, Shabraz, the Skyshark soars into a massive threat, triggering its passive ability on every single card drawn to endlessly pump its power and pad your life total.
