This is a cube designed around synergies and made out of singletons from all the standard legal sets released from Guilds of Ravnica until today. The design goal is to incentify players in building decks that revolve around highly synergic and fun archetypes by providing powerful payoffs and plenty of enablers.
Each color pair is built around its own representative mechanic, skewed more towards aggro and mid-range strategies, but there are a lot of additional themes, build-around and pockets of synergies available within different color combinations, great shells for control deck.
Where possible, archetypes overlap and gain strength in splashing additional colors, hence the presence of 3 dual lands full-cycles and a treasures sub-theme.
