Sensei's Divining Top + Stone Calendar + Mm'menon, the Right Hand

Sensei's Divining Top

Stone Calendar

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 elegant little engine transforms Sensei's Divining Top into a self-sustaining loop by leveraging the topdeck casting enabled by Mm'menon, the Right Hand. Since Mm'menon, the Right Hand also turns your artifacts into mana sources that produce blue mana for spells cast from anywhere other than your hand, you can tap Sensei's Divining Top to draw a card and place itself back on top of your library, using its own generated mana to pay for the subsequent cast. Stone Calendar makes this cycle entirely free by reducing the cost of the Top from {1} to {0}, allowing you to repeat the process indefinitely for infinite card draw, endless draw triggers, and a near-infinite storm count.
