Sensei's Divining Top + Foundry Inspector + Crystal Skull, Isu Spyglass

Sensei's Divining Top

Foundry Inspector

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 clever loop turns your library into a self-replenishing engine by leveraging the top-deck utility of Sensei's Divining Top alongside cost-reduction and card-access effects. Foundry Inspector does the heavy lifting of slashing the artifact's mana value from one down to zero, allowing you to cast it completely for free. Meanwhile, Crystal Skull, Isu Spyglass grants you the crucial permission to play historic spells right off the top of your library while also giving you a helpful tap ability for blue mana if needed. Once everything is in place, you simply tap Sensei's Divining Top to draw a card and place itself back on top, then recast it for free through Crystal Skull, Isu Spyglass, repeating the cycle as many times as you desire to rack up an infinite storm count and draw your entire deck.
