Sensei's Divining Top + Umori, the Collector + Mm'menon, the Right Hand

Sensei's Divining Top

Umori, the Collector

Mm'menon, the Right Hand

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 lets you cycle through your deck endlessly by leveraging the unique advantages of your setup. Mm'menon, the Right Hand is the linchpin of the operation, granting your artifacts a tap ability to produce blue mana specifically for casting spells from outside your hand, while simultaneously letting you play the top card of your library. Meanwhile, Umori, the Collector quietly lightens your mana burdens by making your artifact spells cost {1} less to cast. With those cost reductions and mana generation engines online, you tap Sensei's Divining Top to draw a card and place itself back on top of your library, where you can immediately recast it for free and tap it again for mana and card draw.
