Shouldn't this go in the strategy/moveset board?
For you team, this is what I got
Your slaking has rest, so I'd give it a berry that awakens him so that that's good, for Flygon, I'd get rid of fly and put something else like Sandstorm, get rid of Dragon Claw and put in Dragon Breath. For Swampert check and see which is better, Surf or Muddy Water, and put that in and maybe get rid of roar for rain dance or mud sport.
As for Armaldo, I raised one for the lvl 50 battle tower and here are his moves (No TM's and I kept him for a little bit to learn some moves)
Armaldo @ any of the colloseum berries that up stats, or whatever you want like a white herb
Now your probably thinking that sucks, but Ancient power _can_ up all of his stats and if you use PP UP on it to make more of it, than it's better. I also said that this was with NO TM's so you can add whatever, but I would add some TM's to him, I haven't gotten a chance to do much with mine yet.
I know you probably think my suggestions suck or whatever, but if you think so, then don't listen to them.
