I finally finished the collection of all the shiny Pokémon that can mega-evolve.
This took a lot of trades, some begging, and, of course, luck.
I am almost ready with future mega shiny, and just missing 4 (of the ones currently in the game): Starmie, Heatran, Darkrai, and Crabominable.
Which one is your favorite?
Mine by a long far is Mega Gardevoir
