Mentioning Goomy and its evolutions in the other thread reminded me that I watched the XY series because of this feature and... XY is pretty good! They're certainly not taking the anime in a bold new direction (though the way they handle Mega Evolution is cool), but I caught up to the newer episodes earlier in the year and the series was pretty enjoyable up to that point. Probably gonna wait until they move on to the next series until I start watching it again.
Also, pokepal, yup, that'd be the guy.
