Falco Spara, Pactweaver

Sensei's Divining Top

The Thirteenth Doctor

Helm of Awakening

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. Cast Sensei's Divining Top by paying 0 and removing a counter from a creature you control.
3. The Thirteenth Doctor triggers, putting a +1/+1 counter on it.
4. Repeat.

This brilliant loop transforms Sensei's Divining Top into a free, endlessly repeatable draw engine by utilizing Falco Spara, Pactweaver's ability to cast spells from the top of your library using creature counters as a cost. Helm of Awakening is the crucial cost reducer that drops the Top's casting price down to zero, letting you recast it immediately after drawing it. Meanwhile, The Thirteenth Doctor acts as the engine's catalyst, generating a fresh supply of counters via its Paradox trigger whenever you cast the Top from your library, ensuring Falco Spara always has fuel to keep the chain going.
