Falco Spara, Pactweaver + Sensei's Divining Top + Stone Calendar + Lyla, Holographic Assistant

Falco Spara, Pactweaver

Sensei's Divining Top

Stone Calendar

Lyla, Holographic Assistant

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. Lyla 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 loop turns the top of your library into an endless engine by leveraging Falco Spara, Pactweaver's ability to cast spells using counters instead of mana. With Stone Calendar discounting Sensei's Divining Top down to zero mana, you can continually tap the Top to draw a card and place it on top of your library. Lyla, Holographic Assistant catches each draw trigger to constantly refresh your creature with new +1/+1 counters, which Falco Spara, Pactweaver then happily spends as fuel to recast Sensei's Divining Top right back onto the battlefield.
