White-Black as a color can represent corruption or dishonesty under the clever veil of mercy and/or kindness. It may also represent the balance of good and evil, where the world is seen as a grey area in times of war or strife. As a mechanic, White-black is about gradually killing one's enemies, with white slowing the game down and black destroying opponent's creatures and draining their life totals.
