This is my Pioneer cube! The only rule is that cards must have Pioneer legality. The goal of this cube is to provide a format that is primarily focused on the latest sets while still giving access to classic cube cards. As of the release of Streets of New Capenna the cube is structured as follows:

: Control
: Tempo
: Sacrifice
: Stompy
: Go-Wide
: Aristocrats
: Artifacts
: Graveyard
: Equipment
: Ramp

These archetypes are not set in stone. Due to the nature of adding generically good cards to a cube it is possible to draft lots of unique decks. These archetypes are simply a rough ordering that gives some direction to the cube's design and to the draft.

Feel free to use this cube as a starting point for your own cube. Pioneer is an incredibly diverse format and this cube only scratches the surface of what is possible. Increasing the size to 540 may be preferable so as to show the wide pool of cards available in Pioneer. No matter what you decide to do thanks for taking a look at my cube and if you'd like to give it a draft that would be appreciated. Good luck and have fun!
