Falco Spara, Pactweaver + Sensei's Divining Top + Glaring Fleshraker + Toothy, Imaginary Friend

Falco Spara, Pactweaver

Sensei's Divining Top

Glaring Fleshraker

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 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 loop turns the modest utility of Sensei's Divining Top into an unstoppable engine by leveraging Falco Spara, Pactweaver to cast artifacts directly from the top of your library at the low cost of removing a counter from a creature you control. As you repeatedly draw and recast the Top, Toothy, Imaginary Friend feeds on every card drawn by growing larger with +1/+1 counters, which in turn supply the very counters Falco Spara needs to keep the sequence going. Meanwhile, Glaring Fleshraker watches the colorless Sensei's Divining Top enter the battlefield over and over, spawning Eldrazi tokens that immediately ping your opponents to death and sacrifice themselves to pay the mana required for the next iteration.
