First competitive team

[MajorTemples]

Hello, this is my first team I'm going to make for competitive battling. The pokemon I chose are a selection of the ones I like and are strong at the same time. I think it worked out pretty good but just want some people to check it since I have never done this before.
There are somethings typed bold those are the thing I couldn't figure out myself.
Pokemon, move sets, everything can be replaced if there is a better suggestion/solution.

your team seems pretty solid in my eyes in terms of moves and coverage. in order to get the ability Mold Breaker on your Excadrill, you have to go to the Pokemon Dream World, and hunt for one.

This ingame, not competive.

[MajorTemples]

Well it's meant to be competitive. What would you change?

Nasty Plot seems a little awkward on that Infernape set. If you want something like it, I would recommend a four attack set focusing more on the physical side. This is what I see your infernape doing.

Infernape@Life Orb
Ability:Blaze
Naive Nature
EVs: 252 Spd/252 Atk/4 SAtk
-Fire Blast
-Close Combat
-U-turn
-Stone Edge/Mach Punch

This is not too different from your Infernape. As I switched the EVs from Special Attack to Attack, I switched out Flamethrower for Fire Blast, as its accuracy isn't horrible and it has more power, which is needed. Close Combat is your main STAB fighting attack. It has great power, great accuracy, and a backlash that can be taken easily with U-turn. U-turn does decent damage, but its main reason for usage is to help it escape after its defenses are -2 or below from Close Combat. The last two moves both have their own merits. Stone Edge gives it more coverage in a decently powered move, with a downside of only decent accuracy. Mach Punch is to revenge kill faster pokes and pick off pokes with very low hit points.

Ah true that, I mainly did it so I had a 3 Attackers and 3 Special Attackers.
But since the nasty plot is only working for flamethrower I see why it's better to go for that set, thanks
