Hm... you should go for a Jolteon. Good type coverage! Or perhaps a Flareon? Could be interesting, even though everyone says they suck. Or go for a Leafeon! Oh wait, you can't since no pinwheel forest yet :( Lol I love eeveelutions.
Poor Squishy. But does 43 sound good? Skyla's highest pokemon is 39, so it's well enough above without being to far, good leeway, :D
