Falco Spara, Pactweaver + Sensei's Divining Top + Kappa Cannoneer + Temur Battlecrier

Falco Spara, Pactweaver

Sensei's Divining Top

Kappa Cannoneer

Temur Battlecrier

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. Cast Sensei's Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
3. When Sensei's Divining Top enters, Kappa Cannoneer triggers, putting a +1/+1 counter on Kappa Cannoneer.
4. Repeat.

This clever loop turns the unassuming Sensei's Divining Top into an infinite engine by relying on Falco Spara, Pactweaver to let you cast it directly from the top of your library for zero mana by trading away a counter instead of paying its cost. Every time you recast and resolve the Top, Kappa Cannoneer happily triggers off the artifact entering your battlefield to grow larger and unblockable while fueling your storm count. Meanwhile, Temur Battlecrier lurks quietly in the background, though Falco Spara's alternative cost-paying method makes the Top completely free to recast over and over again.
