Mid range paladin is Ok, it's a nice and viable fun deck for both parties however Mysterious challenger should be a 5/4, if you compare it with Thurissan they have exactly the same effect except that challenger instantly plays what he discounts and there's no reason for it to be stronger stat-wise than a legendary card with the same effect
