No repeat mana symbols of the same color. The absence of heavy color commitment allows for easy 3-4-5-color decks.

Each player gets their choice of either Jegantha, the Wellspring or Golos, Tireless Pilgrim as an extra free card during deck building. Companion rules apply.

During deckbuilding you get your choice of infinite Basic Lands OR Wastes, but not both.

This cube highlights the eternal struggle between multi-colored and colorless throughout Magic's history.
