Sensei's Divining Top + Etherium Sculptor + Skyswimmer Koi

Sensei's Divining Top

Etherium Sculptor

Skyswimmer Koi

How it works

1. Cast Sensei's Divining Top by paying 0 due to Etherium Sculptor.
2. When Sensei's Divining Top enters, Skyswimmer Koi triggers.
3. Holding priority, activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
4. Resolve the Skyswimmer Koi trigger, causing you to draw Sensei's Divining Top from your library, and then discard a card other than Sensei's Divining Top.
5. Repeat

By combining Etherium Sculptor's cost reduction to cast Sensei's Divining Top for free, you set up a brilliant mechanical loop that turns the Top's top-deck ability into a self-contained engine. As you tap Sensei's Divining Top to draw a card and place it back on your library, Skyswimmer Koi triggers upon its re-entry to let you instantly draw the Top right back out of your library while filtering your hand with its discard clause. This clever interplay lets you endlessly cycle through your deck without ever losing your artifacts, generating infinite looting and an astronomical storm count along the way.
