Forum:Evolution

Hi there dear RoD players! I recently did the 4 way evolution twice on Mirrorwater Ring's Mystic Elf !! fully upgraded to 4 star cards, but when i evolve it up to the 4th card, it clearly states that its possible to evolve it one more, cause theres a card that i cant see since i havent upgraded it yet on the evolution phase, but how, since ur 8, 6 and 4 evolution way says that its only possible to evolve to 4th card, but this one shows a fifth card, and i have seen that 5th card on other i have evolved too, i guess it is called (MR = Mega Rare Card) but how to get it ? :o, anyone know how to fully evolve to a MR card ? :) God speed RoD Players and Thanks in Advance
