if you want an advice for team building, you need to show us their movepool too you know @_@. But this team is more balance than the first one for sure.
Actually i can give you this for your team:
With this movepools, you can destroy everything (but it require lots and lots of breeding)
1, Escavalier: (now epi 12.1 Ame had already fixed the Karablast breed egg group, so you can get this):
Megahorn
Poison Jab
Pursuit/ X-scissor/ whatever you like
Sword Dance
(first 2 moves need breeding with Scolipede)
2, Crobat:
Brave Bird
Roost
Cross Poison
Confuse ray/ Mean Lock/whatever you like
(feel free to replace combo BB/ roost with Acrobatic, but i like to give him item like Black Sludge more than nothing)
3, Machamp:
Dynamic Punch (obvious- with No Guard of course)
Bullet Punch (priority and destroy Ice)
Thunder Punch
Ice Punch
(last 3 moves can get through breed with Hitmonchan)
4, Skuntank:
Night Slash
Play Rough
Toxic
Flame Thrower/ Sunny day support/ or anything you like
5, Houndoom:
Flamethrower
Solarbeam
Sunny Day
Dark Pulse
admit it, this is the best moveset he can get. Set up Sunny day even in front of water type. It doesn;t need nasty plot (waste a slot for coverage) Maybe you can use it if skuntank got Sunny day and Heat rock already. But whatever...
6, Blastoise:
it's your starter right?? feel free to whatever you want
This is a well-build team for example. If you can manage it, it'll work very well.
