Oh, and imo Landorus is a bit better than Terrakion because his Ground immunity and Fighting resistance let him come in a lot, and he has Sand Power so he causes lots of switches.
Espeon's ability is cool, so are bulky dragons. Salamence is actually the worst of all of them now, which is surprising (Well, out of Mence, Dragonite, Garchomp, Haxorus). Hazards still work well, but Ferrothorn is a better Spikes user than Skarmory, even though you don't want to use it. SR is still good on anything. Bronzong is good, though it's best run with HP Ice and Earthquake to take out new threats this generation.
Well, I personally always start a team out with Rotom-W, just because imo it's the best all around Pokemon this generation. Then just cover it's weaknesses and such, Scizor makes a great partner for it, along with both Latis, Dragonite, Salamence etc. It's still basically cover your types first, then try to work other thins in.
