Falco Spara, Pactweaver + Sensei's Divining Top + Kianne, Corrupted Memory + Lyse Hext

Falco Spara, Pactweaver

Sensei's Divining Top

Kianne, Corrupted Memory

Lyse Hext

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. Kianne triggers, putting a +1/+1 counter on it.
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. Lyse Hext's prowess ability triggers, giving it +1/+1 until end of turn
5. Repeat.

This loop turns Sensei's Divining Top into a self-replenishing engine by leveraging Falco Spara, Pactweaver's ability to let you cast spells from the top of your library using any creature's counter as an alternate cost. As you repeatedly tap Sensei's Divining Top to draw it and place it back on your library, Kianne, Corrupted Memory pumps itself with +1/+1 counters to keep your power state shifting while providing the draw triggers you need. Meanwhile, Lyse Hext reduces the artifact's cost to zero, making the whole cycle free while triggering prowess repeatedly to grow massively alongside Kianne.
