Wow! I was wary of how M Gardevoir would look, but this is fantastic! Much more glorious than Volcaneon EX, imo. I want like three copies of this, lol.
And the golden egg! That card looks a bit of a mess. It would probably look better if azumarill wasn't shiny, but that gold clashes badly with the pink and blue. Ah well, that's nice it's shiny. I have a shiny azumarill I caught back in Emerald, so this is a nice card for me.
And to join the speculation: I think the other mega may be steelix. It's the only mega that in the movie that has two types that are expressed in the tcg. Gengar is psychic/poison, but poison is expressed as psychic in the tcg, so they can't make it a dual-type card. Same with pidgeot being flying/normal. But steelix is steel/ground, and ground is expressed as fighting, so I think that will be the mega we get.
