Sensei's Divining Top + Herald of Kozilek + Crystal Skull, Isu Spyglass

Sensei's Divining Top

Herald of Kozilek

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 self-sustaining engine by manipulating its own destination. Thanks to Herald of Kozilek reducing the cost of colorless spells by {1}, the Top becomes completely free to recast, eliminating its usual mana tax. Meanwhile, Crystal Skull, Isu Spyglass lets you play historic spells right off the top of your library while also serving as a mana source when needed. By tapping the Top to draw a card and place it on top of your library, you can immediately recast it with the Skull's permission, generating infinite card draw, endless draw triggers, and a near-infinite storm count.
