Sensei's Divining Top + Urza, Lord Protector + The Lunar Whale

Sensei's Divining Top

Urza, Lord Protector

The Lunar Whale

How it works

1. 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.
2. Cast Sensei's Divining Top from the top of your library by paying 0.
3. Repeat

This clever loop turns the top of your library into an endless engine by leveraging the passive abilities of your board. With Urza, Lord Protector actively reducing artifact costs by {1}, Sensei's Divining Top becomes completely free to cast, while The Lunar Whale grants you continuous vision of your topdeck and allows you to play the Top right back off the library the moment it gets put there. By endlessly tapping Sensei's Divining Top to draw a card and slide it back onto your library, you can repeat this cycle to draw your entire deck, generate endless draw triggers, and rack up a massive storm count.
