Sensei's Divining Top + Foundry Inspector + Madame Web, Clairvoyant

Sensei's Divining Top

Foundry Inspector

Madame Web, Clairvoyant

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 the humble Sensei's Divining Top into an endless fountain of card draw by leveraging Madame Web, Clairvoyant to cast it directly from the top of your library and Foundry Inspector to slash its casting cost down to zero. Madame Web, Clairvoyant's ability to let you cast noncreature spells from the library is essential here, allowing the Top to immediately replace itself on top when you tap it to draw. Because Foundry Inspector makes that zero-mana re-cast completely free, you can continuously tap Sensei's Divining Top, draw it, and play it again on repeat for infinite draws and a massive storm count.
