Anger's best interaction is with Enchants. If you can throw an Enchant on one, all of a sudden you're making copies with the Enchant as well, and that can get out of control quickly. Also does well with Card Draw, Strength, and some Relics or Cards which care about playing multiple Attacks in a turn. /Usually/ this can just be evaluated as a 0-Cost deal 6, which is ~okay. Occasionally it does much more than that, but don't expect that to happen very often.
A remarkably flexible attack that can be used for free damage early game as well as being an endgame damage plan with Strength and card draw. Combine with Vicious, Pillage, or Battle Trance to draw the growing pile of attacks. Sometimes you should refrain from playing this card if additional copies would be disadvantageous.
