Falco Spara, Pactweaver + Sensei's Divining Top + Starnheim Courser + Lorescale Coatl

Falco Spara, Pactweaver

Sensei's Divining Top

Starnheim Courser

Lorescale Coatl

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. Lorescale Coatl 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 clever setup turns Sensei's Divining Top into a self-sustaining engine by letting you repeatedly cast it for free. Falco Spara, Pactweaver enables you to bypass its normal mana cost by playing it directly from the top of your library while cashing in a counter from a creature, a cost further reduced down to zero thanks to Starnheim Courser discounting artifact spells. Every single time you loop this sequence, Lorescale Coatl happily grows larger with a brand new +1/+1 counter every time you draw.
