Yeah, I'm afraid the mechanics are easily recognizable as a LOTR TCG rip off, if I'm guessing them correctly, which would kinda doom your project, if you're not careful and legally assisted. Have you cleared it with a copyright attorney?
I mean, there are only so much game mechanics anyway (and Magic has used them all at one point or another, if you look too closely at it), so repeats are bound to happen, but I'd shield myself before starting playtesting (which indicates an advanced progress and that the product is almost ready to go live).
