Zwart

Black is the color of self-indulgence, parasitism, amorality and unfettered desire for power. It believes that the world is made for its taking and that the weak exist to be exploited by the strong. The essence of Black is to see one's own ego as so supremely invaluable, that the prospect of enslavement, of subordinating that ego to another, is utterly inadmissible. So, to be in accord with its perceptions and beliefs, Black simply must discard all obligations but to acquire power for itself. It can be no less than the one supreme being who is subordinate to no other, the possessor of all power in the universe - it must become omnipotent.

Mechanics

Creature destruction, including toughness reduction: Black is the color that most embraces death as a tool. It sees the ability to take a life as exerting the greatest power over others, and so will ruthlessly demonstrate this power against its enemies. Examples: Sudden Death, Dark Banishing.

Discard: Black is able and willing to cause mental trauma to others. As a result, black can cause its opponents to discard cards. Examples: Mind Rot, Hypnotic Specter.

Reanimating creatures: Black has no compassion for the dead, nor any moral inhibitions about exploiting them. As a result, black will force its creatures (or even those of its enemies) to serve it even from beyond the grave. Examples: Zombify, Animate Dead.

Sacrificing itself and others for power: Black will not turn down any opportunity to gain power, even if it comes at great personal risk. As a result, black will enter into agreements with powers other colors would never go near. This gives black access both to under-costed creatures and powerful effects such as card drawing, but they are balanced with dangerous drawbacks. examples: Dark Confidant, Lord of the Pit.

Draining life from others: Black is parasitic in nature, growing through taking from others. Its ability to siphon life from creatures and players is reflective of this. Examples: Soul Feast, Consume Spirit.
