Falco Spara, Pactweaver + Sensei's Divining Top + Glaring Fleshraker + Chasm Skulker

Falco Spara, Pactweaver

Sensei's Divining Top

Glaring Fleshraker

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 1 and removing a counter from a creature you control.
4. Glaring Fleshraker's first ability triggers, creating a 0/1 Eldrazi Spawn creature token.
5. When the Eldrazi Spawn enters, Glaring Fleshraker's second ability triggers, dealing 1 damage to each opponent.
6. Activate the Eldrazi Spawn by sacrificing it, adding C.
7. Repeat.

This ingenious loop turns Sensei's Divining Top into a self-sustaining engine by utilizing Falco Spara, Pactweaver's static ability to let you cast spells straight from the top of your library while paying costs by removing counters from your creatures. Every time you draw the Top, Chasm Skulker dutifully grows bigger with a brand-new +1/+1 counter, ensuring you never run out of fuel to remove. Meanwhile, Glaring Fleshraker watches over the entire process, rewarding your endless recast of the artifact with an Eldrazi Spawn token that both provides the mana needed to replay it and deals unescapable damage to your opponents upon entry.
