Sensei's Divining Top + Cheering Fanatic + Skyswimmer Koi

Sensei's Divining Top

Cheering Fanatic

Skyswimmer Koi

How it works

1. Declare Cheering Fanatic as an attacker. When it triggers, choose to name "Sensei's Divining Top".
2. Cast Sensei's Divining Top by paying 0 due to Cheering Fanatic.
3. When Sensei's Divining Top enters, Skyswimmer Koi triggers.
4. 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.
5. 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.
6. Repeat from step 2

This clever setup turns a modest artifact into a self-sustaining engine by taking advantage of cost reduction and draw manipulation. **Cheering Fanatic** does the heavy lifting before the turn even progresses to damage, using its attack trigger to name "Sensei's Divining Top" so that the artifact can be recast for free. As each new copy drops onto the battlefield, **Skyswimmer Koi** provides the crucial background engine by triggering off the entering artifact, letting you churn through your library with loot effects. By responding to that triggered ability with **Sensei's Divining Top**'s own tap ability, you draw a card while tucking the Top safely back on top of your deck just in time for the Koi's resolution to draw it right back out—yielding endless triggers, discarded cards, and a soaring storm count.
