I also would like help with Lucario's moveset. Whats a better alternative to Dragon Pulse? I never end up using it, but I don't know what to switch it with.

So far, I love your team. Each Pokemon is there to support one another. This is a necessary synergy for teams, and you have it.

Now, concerning Lucario, Dragon pulse should be replaced with Extreme Speed, to give him a powerful move with priority. If extreme speed isn't your thing though, try Water Pulse for coverage and confusion chance.

Your team is very nice. But why the Gentle nature on Zapdos ? I suggest a Calm nature to further boost its Special Defense .
