Sensei's Divining Top + Skyswimmer Koi + Armor Wars

Sensei's Divining Top

Skyswimmer Koi

Armor Wars

How it works

1. Cast Sensei's Divining Top by paying 0 due to Armor Wars.
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 ingenious loop transforms your library into an endless card-drawing engine by leaning into the cost-reduction power of Armor Wars's second chapter to cast Sensei's Divining Top for free. As the Top enters the battlefield, Skyswimmer Koi triggers to let you draw and discard, but before that trigger resolves, you tap the Top to draw a card and place it right back on top of your library. When the Koi's triggered ability finally resolves, you draw Sensei's Divining Top back into your hand, allowing you to repeat the cycle indefinitely for boundless looting and storm count.
