Falco Spara, Pactweaver + Sensei's Divining Top + Semblance Anvil + Toothy, Imaginary Friend

Falco Spara, Pactweaver

Sensei's Divining Top

Semblance Anvil

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 clever engine lets you draw your entire deck by looping Sensei's Divining Top entirely for free. With Semblance Anvil having exiled an artifact to reduce artifact spell costs by {2}, tapping Sensei's Divining Top to draw a card and place it on top of your library allows you to cast it right back off the top thanks to Falco Spara, Pactweaver's ability to pay for spells by removing a counter from a creature you control instead of paying mana. Every time you draw that card, Toothy, Imaginary Friend triggers to grow larger with a +1/+1 counter, fueling an endless cycle of artifact entry and exit triggers.
