With the remaining Megas yet to be revealed, I'm gonna predict that it will be Manectric, because there could be an opportunity for Ampharos to be a Dragon type, and there is also Charizard X as well.
EDIT: Thinking on from Ampharos, we could also see a Fighting type Mewtwo X in the near future...
In the core games he would, but in the Trading Card Game, Mega Alakazam ex will be released as a Stage 2 Pokémon that is the evolved form of Kadabra, which will have a tag that says "The Mega-Evolved form of Alakazam" underneath the HP. Perfect examples of this would be Mega Lucario ex and Mega...
Mega Absol ex and Mega Camerupt ex have both been revealed for this set. Although speculative at this point, Mega Abomasnow ex and Mega Mawile ex have also been revealed. The number of Mega Pokémon ex that will be released so far is 9 out of 46, though this 46 number will be higher if there are...
Bulbasaur, Ivysaur, Mega Venusaur ex, Vulpix, Ninetales, Sobble, Drizzile, Inteleon, Pachirisu, Ralts, Kirlia, Mega Gardevoir ex, Riolu, Mega Lucario ex, Mega Latias ex, and Latios have been revealed today for this set.
If Frillish and Jellicent are 44 and 45 respectively, but are 41 and 42 respectively, that means that three of the Black Bolt card will be transferred to White Flare when it's released in English.
The one thing I don't get is why have Mega Lucario and Mega Gardevoir evolve from Riolu and Kirlia respectively when they cannot skip the Lucario and Gardevoir stages respectively in the games? That literally makes no sense at all.
The whole set has now been revealed. And I can honestly say that for a good majority of them, the opportunity to represent their other type has been badly missed, especially in Victini, Ferroseed and Ferrothorn, which for me is a real shame.
