John Terrill of Cultic Cube (https://www.youtube.com/culticcube) curates an unpowered vintage cube that features robust support for the pillars of Magic game play and largely shies away from narrow archetypes. This encourages game play that is extremely interactive and that plays to the board, minimizing strategies that approximate solitaire. Aggro, Midrange, and Control are all viable approaches, underpinned by broad access to functionally similar components.
