Artifact spells cost less to cast.
Whenever chaos ensues, creatures you control that are white, blue, and/or black become artifacts in addition to their other types until end of turn. Then each artifact creature you control gains vigilance (Attacking doesn't cause this creature to tap.), menace (This creature can't be blocked except by two or more creatures.), and lifelink (Damage dealt by the creature also causes its controller to gain that much life.) until end of turn.
