Falco Spara, Pactweaver + Sensei's Divining Top + Surge Conductor + Helm of Awakening

Falco Spara, Pactweaver

Sensei's Divining Top

Surge Conductor

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 Diving 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 the battlefield, Surge Conductor triggers, putting a counter on a creature you control that already has a counter on it.
4. Repeat.

This intricate engine turns the top of your library into an endless card-drawing machine by turning Sensei's Divining Top into a self-replacing spell. While Helm of Awakening reduces the artifact's mana cost down to zero, Falco Spara, Pactweaver allows you to cast it directly from the library by paying that zero cost and removing a counter from a creature you control. Whenever Sensei's Divining Top re-enters the battlefield, Surge Conductor’s static-triggered ability catches the new artifact and proliferates, immediately replacing the counter you just spent to keep the loop going.
