Hey CommonCommander here.
This is a pEDH cube, that means the goal is to build a deck using the EDH rules (commander, colour identity, etc) but with any uncommon as the commander and only commons in main deck. If you’re interested in pEDH checkout the PDH Home Base. https://www.pdhhomebase.com/

Goals

The goal of this cube is to embody the wonder of pEDH at all levels of power. As such many combos are possible and supported, tutors and the fastest mana we have are included too. Pulling off combos will be more risky than jamming decent creatures but has a higher pay off if drafted. This feeling may take balancing to manage if combos are too easy/hard to pull off.

The draft works as follows:

Each player receives 4 “packs”; 1 commander pack (containing 6 uncommon creatures) and 3 normal packs (20 cards all common)

The commander pack is drafted first, each player selects 1 card to put into their card pool. If you choose a “partners with” card the partner will be provided (only 1 half of each partner pairing is included in packs.)

Once the commander pack is complete the draft continues with the same style draft as Commander Legends, each player takes 2 cards and passes it on.

At the end you will have 6 commander options and 60 commons, you’re deck must be 60 cards following pEDH rules (uncommons cannot be in main deck, colour identity applies and commoners count towards deck count.) Any player may choose to play the Prismatic Piper as a commander, including partnered with another of itself.

After drafting is complete you play games however you’d like. The cube is created with 4 player in mind but shouldn’t be too restrictive.
