Falco Spara, Pactweaver + Sensei's Divining Top + Glaring Fleshraker + Lyla, Holographic Assistant

Falco Spara, Pactweaver

Sensei's Divining Top

Glaring Fleshraker

Lyla, Holographic Assistant

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. Lyla 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 intricate loop turns the classic Top-into-library trick into a lethal engine by leveraging Falco Spara, Pactweaver's ability to cast spells straight from the top of your library using creature counters as an alternative cost. Every time you cast Sensei's Divining Top, Glaring Fleshraker spots the colorless spell and rewards you with an Eldrazi Spawn token, which can then be sacrificed for the mana needed to replay it. Meanwhile, Lyla, Holographic Assistant keeps the counter supply healthy by dropping a +1/+1 counter onto your creatures whenever you draw a card, perfectly fueling Falco's casting requirement for the next iteration. As you repeat this cycle, Glaring Fleshraker's second ability continuously triggers off the entering tokens to drain your opponents' life totals down to zero.
