Is this Pokemon team good?

I would try getting rid of either Alakazam or Gengar, since if you're battling a Psychic/Ghost type, half your team is pretty much dead. I suggest keeping Alakazam and teaching it Shadow Ball, and then taking away Gengar since I think they're pretty much the same but Alakazam has high speed & special defense. I would also get try and get another Fire-type move on Infernape that doesn't give you recoil damage or is risky. Flamethrower is a nice move. Other than that, I think your team is pretty much good.
