Sensei's Divining Top + Skyswimmer Koi + Shuri, Wakandan Inventor

Sensei's Divining Top

Skyswimmer Koi

Shuri, Wakandan Inventor

How it works

1. Cast Sensei's Divining Top by paying 0 due to Shuri.
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

This clever loop turns the unassuming Sensei's Divining Top into an infinite card-churning engine, fueled entirely by stacking replacement and resolution triggers. Shuri, Wakandan Inventor provides the crucial cost reduction that makes Sensei's Divining Top free to cast, meaning it can enter the battlefield repeatedly without draining your mana. Every time it drops, Skyswimmer Koi triggers to let you draw and discard, and by tapping Sensei's Divining Top in response to put itself back on top of your library, the Koi's resolution draws it right back out again. Through this clever sequencing, you get to cycle through your entire deck while discarding whatever you please, racking up a massive storm count along the way.
