This cube aims to maximize the powerlevel of a format where all macro-archetypes are supported and everything can interact with each other.
Combos are confined to strategies that cheat big creatures into play, as to allow counterplay.
Mana acceleration must come with a downside: either it is mana negative the turn you play it (signets), or it has some additional drawback (Mana Vault does not untap, Chrome Mox is card disadvantage).
