Sensei's Divining Top + One with the Multiverse + Gran-Gran

Sensei's Divining Top

One with the Multiverse

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's top card into a self-sustaining engine by exploiting the interaction between Sensei's Divining Top and the continuous permission granted by One with the Multiverse. Tapping the Top sends it to the very top of your library, exactly where One with the Multiverse allows you to immediately cast it again. Meanwhile, Gran-Gran provides vital support by reducing the artifact's mana cost, ensuring you can repeatedly cast and tap Sensei's Divining Top without running out of resources while cycling through your deck for infinite card draw and storm count.
