Falco Spara, Pactweaver + Sensei's Divining Top + Ugin, the Ineffable + Chasm Skulker

Falco Spara, Pactweaver

Sensei's Divining Top

Ugin, the Ineffable

Chasm Skulker

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. Chasm Skulker 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. Repeat.

This delightful looping engine turns your library into an endless well of card draw by leveraging Falco Spara, Pactweaver's remarkable ability to let you cast spells directly from the top of your deck using creature counters as an alternative payment. Sensei's Divining Top naturally feeds this cycle by replacing its own draw with a trip back to the top of your library, allowing you to continually recast it for free by stripping counters away from your creatures. Meanwhile, Chasm Skulker happily grows larger with every single card drawn during the process, ready to flood the board with a massive swarm of Squid tokens if it eventually perishes. To keep the engine running smoothly without draining your mana reserves, Ugin, the Ineffable steps in with his passive cost-reduction, ensuring the colorless Top can be replayed entirely for free over and over again.
