This is humorous, because everytime I hear stuff like this, I think of spoils. I had spoils, both boxes marked, on one of my units in a game this weekend. I promptly failed. Now THAT's BS.
Anyway, back to oathbound. Hell, I think that card is decent. The biggest weakness is that you have to play it proactively instead of reactive. (which, I'll agree, is a big difference) I wouldn't change it at all.
