The reward cards will never have great value as I believe their main two reasons for being in existence is to be combined and to get you to buy booster packs. While I wouldn't recommend them as a potential income producer on their own they can be very helpful for someone that is not specializing in one or two splinters but is playing a more general game using all splinters and then flipping higher value reward cards to buy beta (or alpha) cards.
