The main philosophy behind building this cube is that most of the cards are supposed to be very close in power level. This has lead to cutting some of the more overpowered stuff like Sol Ring, Skullclamp and Demonic Tutor
As the power level is equalized, the focus of decks rely largely on synergies and finding the perfect balance between spells and creatures, mana curve and optimal mana base.
All this should lead to a very enjoyable format that feels like powerful limited magic.
It is possible to draft any color combination here.
