Sensei's Divining Top + Starnheim Courser + Crystal Skull, Isu Spyglass

Sensei's Divining Top

Starnheim Courser

Crystal Skull, Isu Spyglass

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 elegant little loop turns Sensei's Divining Top into a free, self-replacing spell by leveraging cost reduction and topdeck playability. With Starnheim Courser discounting artifact spells by {1}, Sensei's Divining Top's normal casting cost of {1} is reduced to zero. Meanwhile, Crystal Skull, Isu Spyglass grants you the crucial ability to cast historic artifacts directly from the top of your library while also providing blue mana if needed. When you tap Sensei's Divining Top to draw a card and place it on top of your library, you can immediately cast it again for free, triggering infinite card draws and an astronomical storm count.
