What should my other pokemon be and is my team good?

I like your team. It looks really good. Nice type balancing. Get Alakazam's defense up. It has the same nature like the Espeon I have (Lv100) and I had the same issue with both normal and Special Defense. Get a Swampert to add to your team if you've defeated the game. A Charizard to get a Fire-type AND Flying-type in there would be really nice too. As for your final Pokemon, that's really tough. Umbreon's great, but it shares too many weaknesses with the team members you've already posted. Get a Dragon-type in there (Besides, it can help with your other members of your team. Having it in there plus a Fire-type means a KILLER team). It's tough to decide which Dragon-type to put in there. I suggest a pure Dragon-type (no secondary weaknesses; otherwise, it'll REALLY mess up your team)). If you want to figure out for yourself for what pure Dragon-type you want, go to serebii.net.
