I must agree with Peralisc that some of the wild dogs need to be changed, particularly shadow hound and black hound, summoned hound to a lesser extent.
In my experience, you are usually better of just attacking with cards such as summoned hound than focusing (I wont go on about this for the sake of simplicity), and risk the card being targeted by an open skill or SS the next turn. So I think the hounds should step away from the clunky focus mechanic and focus on the theme of attack drain (or whatever you want to call it).
IMO black hound's auto skill could be changed to a start, and make it target, if that is considered to much, then at least make it drain att from something with att > 0.
Shadow hound could have its focus/action skill removed, give him 2 range (take a stat point away from elsewhere if you must) and give him an action skill:
Do damage att to one enemy unit of att = 0.
This is just of the top of my head so it could probably do with some refinement, but you get the idea.
