This is an important piece for most Avarice decks that are slower. This gives both a way of getting rid of an important threat for a small amount of time but also a blocker during that time.
Against most Penance and Decay (and to a lesser extent, Fighters) will make short work of the Unit but against other Attributes, this will prove to be a very reliable removal spell.
