Falco Spara, Pactweaver + Sensei's Divining Top + Wizard Class + Herald of Kozilek

Falco Spara, Pactweaver

Sensei's Divining Top

Wizard Class

Herald of Kozilek

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. Wizard Class triggers, putting a +1/+1 counter on a creature you control
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-sustaining engine by letting you repeatedly draw it and recast it for free. Falco Spara, Pactweaver is the linchpin of this operation, allowing you to cast the Top directly off the top of your library by consuming counters instead of paying mana. Meanwhile, Wizard Class provides the crucial bridge by feeding Falco Spara, Pactweaver fresh +1/+1 counters every time you draw a card, replacing the counters you spend to cast the Top. To make the math work seamlessly, Herald of Kozilek reduces the casting cost of the colorless artifact down to zero, ensuring you can endlessly repeat the cycle without ever running out of mana or resources.
