Falco Spara, Pactweaver + Sensei's Divining Top + Herald of Kozilek + Stark's Ingenuity

Falco Spara, Pactweaver

Sensei's Divining Top

Herald of Kozilek

Stark's Ingenuity

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. Stark's Ingenuity triggers, putting a +1/+1 counter on the creature it's attached to
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 exploiting the synergy between Sensei's Divining Top and Falco Spara, Pactweaver, which lets you cast spells straight from the top of your library by stripping away a counter from a creature. Ordinarily you'd run out of fuel, but Stark's Ingenuity continuously replenishes your supply by dropping a fresh +1/+1 counter onto the enchanted creature every time you draw a card. Meanwhile, Herald of Kozilek quietly does the heavy lifting in the background, reducing the cost of colorless spells so that casting Sensei's Divining Top from the top of your library becomes completely free.
