Similar to Bravo, but much more reactive and restricted. Because it is a trifle, you can put it into play much easier than many other archetypes in this list.
I see this card as being useful for the various Sabbat combat clans that cannot prevent or deal with Strike: Combat Ends, such as the Ahrimanes, Tzimisce and !Gangrel. However, gaining a blood when your victim eludes you seems a poor compensation for what is essentially a failed combat. Still, if they're going to get away from you, you might as well get something for your troubles.
One benefit of this card over others is that it can be used on each Methuselah's turn, including your own.
So using Ahrimanes as an example. Howler enters combat with your prey's vampire on your turn, gains a blood when Gilbert Duane runs away by playing a Dodge. Then, on your prey's turn Howler wakes and blocks Gilbert the sissy sneak-bleeder once again. Gilbert runs away again, playing a Dodge like the coward he is. Howler gains another blood. Then on your predator's turn, you block some other sneak-bleeding scumbag (or try to).
Still, if you're biggest concern is dealing with dodges and combat ends cards, you're probably better off playing with a different deck type altogether in my opinion.
