Falco Spara, Pactweaver + Sensei's Divining Top + Toothy, Imaginary Friend + Starnheim Courser

Falco Spara, Pactweaver

Sensei's Divining Top

Toothy, Imaginary Friend

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. Toothy triggers, putting a +1/+1 counter on it.
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 turns your library into an endless carousel by leveraging Falco Spara, Pactweaver to cast spells straight from the top while burning away the creature counters your board accumulates. Sensei's Divining Top acts as the core projectile, drawing you a card and replacing itself on top of your library repeatedly, a loop whose mana cost is completely erased thanks to Starnheim Courser discounting it down to zero. Meanwhile, Toothy, Imaginary Friend sits back and quietly absorbs all those card draws as an ever-growing pile of +1/+1 counters—counters that happily double as the fuel Falco Spara needs to keep casting the Top over and over again.
