Sensei's Divining Top + One with the Multiverse + Samut, the Driving Force

Sensei's Divining Top

One with the Multiverse

Samut, the Driving Force

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 transforms a humble artifact into an endless engine of card advantage by leveraging the top of your library as a hidden hand. With One with the Multiverse granting you the ability to cast spells directly from the top of your library—and allowing your first spell each turn to be cast completely free—you can cast Sensei's Divining Top for zero mana. Once it's on the battlefield, tapping Sensei's Divining Top draws you a card while tucking itself safely back onto the top of your library, ready to be cast again. Meanwhile, Samut, the Driving Force quietly accelerates your mana economy by reducing the cost of noncreature spells by an amount equal to your speed, ensuring that even if you aren't using your free turn-based cast, the loop remains extraordinarily cheap or entirely self-sustaining.
