Falco Spara, Pactweaver + Sensei's Divining Top + Toothy, Imaginary Friend + Stenn, Paranoid Partisan

Falco Spara, Pactweaver

Sensei's Divining Top

Toothy, Imaginary Friend

Stenn, Paranoid Partisan

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 turns Sensei's Divining Top into a self-sustaining engine by letting you draw it and replay it entirely for free. Stenn, Paranoid Partisan quietly slashes the artifact's mana cost down to zero, while Falco Spara, Pactweaver lets you cast it directly off the top of your library by trading away one of the +1/+1 counters that Toothy, Imaginary Friend happily accumulates with every single card you draw. As Toothy grows larger and larger from the draw triggers, you churn through your entire deck to generate a massive storm count and endless artifact triggers.
