Ok, for clarification. If you read the details of the R8 under Rewards, this card will not be given out, so it is just showing you the artwork. Why they bothered changing it to say x4 is beyond me, but it is DeNA / Mobage and the dev team rarely have a clue. So definitely seems you evolve the 4 cards through the different Rarity levels.
