This clever loop lets you spin through your entire deck by exploiting a classic cost-reduction trick with Sensei's Divining Top. With Stenn, Paranoid Partisan on the board naming "artifact" to make your artifacts cost {1} less, the Top's normal casting cost of {1} is entirely wiped away to {0}. Meanwhile, Madame Web, Clairvoyant provides the crucial advantage of letting you peer at and cast artifacts directly from the top of your library, meaning every time you tap Sensei's Divining Top to draw a card and place itself back on library, you can immediately cast it again for free.
