Falco Spara, Pactweaver + Sensei's Divining Top + Yotian Dissident + Etherium Sculptor

Falco Spara, Pactweaver

Sensei's Divining Top

Yotian Dissident

Etherium Sculptor

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 from the top of your library by paying 0 and removing a counter from a creature you control.
3. When Sensei's Divining Top enters, Yotian Dissident triggers, putting a +1/+1 counter on Yotian Dissident.
4. Repeat.

This intricate setup lets you draw your entire deck and cycle artifacts endlessly by leaning on Falco Spara, Pactweaver to cast spells straight from the top of your library using counters instead of mana. Etherium Sculptor is the crucial cost reducer that makes Sensei's Divining Top free to cast, while Yotian Dissident turns each re-entry of the Top into a fresh counter source to feed right back into Falco Spara, Pactweaver's alternate casting cost. You simply tap Sensei's Divining Top to draw a card and place it on top of your library, recast it for free by removing that newly placed counter, and watch Yotian Dissident trigger to replace it, creating a self-sustaining loop of card draw and artifact triggers.
