Falco Spara, Pactweaver + Sensei's Divining Top + The Immortal Sun + Toothy, Imaginary Friend

Falco Spara, Pactweaver

Sensei's Divining Top

The Immortal Sun

Toothy, Imaginary Friend

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 loop transforms the top of your library into an engine of endless card advantage by leveraging Falco Spara, Pactweaver's ability to cast spells using creature counters as an alternative cost. Sensei's Divining Top acts as the core recurrence piece, repeatedly drawing a card and putting itself back onto your library while simultaneously fueling Toothy, Imaginary Friend's massive growth through its card-draw trigger. To make this loop cost nothing, The Immortal Sun swoops in with its passive cost reduction, shaving the {1} generic mana requirement down to zero so you can recast the Top for free.
