Falco Spara, Pactweaver

Sensei's Divining Top

Semblance Anvil

Chasm Skulker

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. Chasm Skulker 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 elegant loop lets you draw your entire deck and cycle Sensei's Divining Top infinitely by leaning on a clever cost-reduction engine. With Semblance Anvil already discounting artifact spells by two mana, tapping Sensei's Divining Top lets you draw a card—which triggers Chasm Skulker to grow with a new +1/+1 counter—and then return Sensei's Divining Top right to the top of your library. From there, Falco Spara, Pactweaver lets you cast that very same artifact off the top of your library for free by using the counter you just placed on Chasm Skulker as alternative payment.
