Sensei's Divining Top + The Lunar Whale + Gran-Gran

Sensei's Divining Top

The Lunar Whale

Gran-Gran

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 your library into an endless card-drawing engine by weaponizing the interaction between Sensei's Divining Top and a deeply discounted casting cost. While Gran-Gran's passive ability provides the crucial cost reduction that makes Sensei's Divining Top free to cast, The Lunar Whale lets you track the top of your library at all times and play cards directly from it once it has attacked. By tapping Sensei's Divining Top to draw a card and place itself back on top of your library, you can immediately recast it for free using Gran-Gran's discount, repeating the process as many times as you desire for infinite card draw, draw triggers, and storm count.
