Check out my 40 card expansion which adds Initiative/Monarch cards as well as more multicolored guild support here: https://cubecobra.com/cube/list/3hwv9

This is my Pauper Cube, which attempts to provide the most fun custom Limited format based on the most powerful and iconic commons throughout Magic's history.

The rules are as follows:

• MTGO/MTGA-only commons are allowed

• cards banned in Pauper Constructed are generally allowed

• exact functional reprints and strictly worse versions of cards are excluded for variety

• Un-sets are banned

• cards with the type Conspiracy, Phenomenon or Plane are banned

10 sample decks for the 10 guild archetypes can be found here:
