Age of Kings
of the Ash Legion
I agree with the mention of Kanga, Scolipede, Galvantula, Charizard, Azumarill, etc and I don't want to reiterate what's been done to death so I'll bring up a few "lesser" picks.
1. Blastoise. One of the "dark horse" mega evos that seemed to escape great notice but a Spinner with 79/120/115 defenses with great typing and 135 SpA to discourage switch-ins is amazing to say the least. Base 78 speed isn't horrible for a Pokemon with this kind of build either (beats Heatran by one point). It also got a few new toys in Aura Sphere, Dragon Pulse, and Dark Pulse that allow it to shit on every spinner barring Tentacruel and not suffer from the Ice Beam/Surf/Hydro Pump/Hidden Power nerfs as badly as other Water types *cough*Keldeo*cough*. For this reason you don't even have to use it as a Spinner, just a good bulky Water that dishes out good damage and can force switches with Yawn to keep your enemies on their toes. Since XY seemed to have cut down on the power creep, I think that the meta will be welcoming to mega Blastoise.
2. I think Gamefreak threw Empoleon a few bones. Its defensive typing is immensely useful in the environment XY is shaping up to be and it got Defog, fearing little from three of the four entry hazards. Latias has difficult typing to work around from a defensive standpoint and cannot set up Rocks, leaving a niche for Empoleon to fill. It remains to be seen how it fares but I wouldn't discount it yet.
uhhhh all I can think of for now. :P I'll try to think of something that isn't a Water type.
