Falco Spara, Pactweaver + Sensei's Divining Top + Semblance Anvil + Captain Storm, Cosmium Raider

Falco Spara, Pactweaver

Sensei's Divining Top

Semblance Anvil

Captain Storm, Cosmium Raider

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, Captain Storm triggers, putting a +1/+1 counter on Captain Storm.
4. Repeat.

This loop creates a perpetual motion machine by turning Sensei's Divining Top into a zero-mana self-replacing spell. With Semblance Anvil having exiled an artifact to reduce artifact spell costs by {2}, the Top's mana value drops from one down to free. Falco Spara, Pactweaver lets you cast that top card directly off your library while fueling the casting cost by stripping away counters instead of paying mana. Every time Sensei's Divining Top re-enters the battlefield, Captain Storm, Cosmium Raider triggers to replenish the counter supply on herself, ensuring you never run out of fuel to keep drawing your deck and triggering infinite artifact entries.
