Falco Spara, Pactweaver + Sensei's Divining Top + Shabraz, the Skyshark + Foundry Inspector

Falco Spara, Pactweaver

Sensei's Divining Top

Shabraz, the Skyshark

Foundry Inspector

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 clever loop transforms Sensei's Divining Top into a self-replacing engine by letting you repeatedly draw it and recast it for free. Foundry Inspector removes the artifact's mana cost entirely, while Falco Spara, Pactweaver provides the alternate payment by stripping counters off your creatures instead of spending mana. Meanwhile, Shabraz, the Skyshark capitalizes on every single iteration of this cycle, growing into an infinitely massive threat and netting you infinite life along the way.
