Try to stay away from having 2 of the same types of moves. And always try using moves with good reliable accuracy. Because you never know when you'll need another move type to cover your Pokemons weakness. In example, lets say your last healthy Pokemon is Pikachu, and it has Thunderbolt and Thunder as it's only attacking moves, and your opponent sends out Excadrill. Ground nullifies your electric moves, so you really need an mixed-type moveset.
A good moveset for Emboar is:
Hammer Arm - already low speed, good power, STAB
Earthquake - amazing move, coverage
Wild Charge - covers flying and water weakness (goodbye pelipper and swanna!)
Flare Blitz - high hp so recoil doesn't matter too much, STAB, strong move
For your Sawk:
Close Combat - good move, high power, STAB
Rock Slide/Stone Edge- lower power with accuracy, or higher power with lower accuracy? Your choice. Also covering flying weaknesss
Payback/Fling - covers psychic weakness. payback is reliable, but weak, but Fling (with the Heavy Rock or something like that) is powerful and a dark type
Earthquake - coverage
Fusion Flare/Flamethrower - your choice, STAB on both
Dragon Pulse- amazing, STAB
Shadow Ball/Psychic - coverage, your choice
Focus Blast - for those Tank-ish rock and normal types
Dark Pulse - STAB, good sp. atk
Dragon Pulse - STAB
Ice Beam - coverage and for other dragons
Focus Blast/Psychic/Flamethrower - all coverage
Seed Bomb/Solar Beam - STAB, good move.
Leech Seed/Sunny Day - hp regain or help with solar beam?
Nasty Plot/Work Up - depending on your choice of seed bomb or solar beam. you can breed a male Weavile (evolve sneasel at night with razor claw) and a female pansage for Nasty Plot.
Rock Slide- covers all weaknesses
Waterfall - STAB, good move, may cause the target to flinch
Horn Attack - good move, neutral damage
Megahorn - covering grass weakness
Aqua Ring/Mud Shot - healing or covering your electric weakness? your choice, but mud shot has to be bred into it.
Your on-the-field moves can be taught to a useless other pokemon in your party (that's what I do).
I train at the Nimbasa City stadiums and the Royal Unova (where I have my official team); other wise I'm goofing off by breeding or finding items and what not.
I hope I helped!
