Prime, Megatron, Grimlock, Starscream, Shockwave, and Soundwave would be six that I would concentrate on. In the beginning really any R3 is good to MTM. Any of them will increase your deck power. Ultra Magnus isn't as good as he should be for some reason. As for now I'd MTM any R3 that you find a set for. Eventually you'll get them all and pick up some R4 rewards with a stronger deck.
