Falco Spara, Pactweaver + Sensei's Divining Top + Kykar, Wind's Fury + Oneirophage

Falco Spara, Pactweaver

Sensei's Divining Top

Kykar, Wind's Fury

Oneirophage

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. Oneirophage 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. Kykar triggers, creating a 1/1 Spirit creature token.
5. Activate Kykar by sacrificing the Spirit, adding .
6. Repeat.

This engine turns the humble top of your library into an endless workshop by letting Falco Spara, Pactweaver constantly cast Sensei's Divining Top from the library at the bargain price of removing a counter from any creature you control. Each time you draw and recast the Top, Kykar, Wind's Fury generates a Spirit token that can be immediately sacrificed for red mana to pay the {1} casting cost, neatly covering the expenses of the loop. Meanwhile, every card drawn feeds Oneirophage's steady growth, piling up +1/+1 counters that can be spent right back to fuel Falco's alternate casting costs.
