Ok enough about which is better or worse its not competetive battling its ingame all of the pokemon are good otherwise they wouldnt have made them. I say if you like using Unfezant use it bc it's base 105 atk is nothing to shake a stick at. Use Tailwind for speed boosting in case it faints so u can revenge kill. U-Turn out or deal major damage with Acrobatics. Roost off damage, or Facade Status afflictions for boosted STAB damage. Basic as that. You can also pick this pokemon up early so for earl training.
Unfezant
Acrobatics
Roost/Facade
U-Turn
Tailwind
In Pinwheel forest catch a Sewaddle and evolve it to Swadloon. Train with it there for a happiness boost and find lots of feathers on the bridge to give to it for another happiness boost. When it evloves into Leavanny teach it Swords Dance, Leaf Blade, X-Scissors, and False Swipe. Yes, I said False Swipe, it's ingame and you have top catch other pokemon not just battle so False Swipe is a good move to learn. I'm not saying keep it all the way till the end just until u have your pokemon you want thats all.
Leavanny
Swords Dance
Leaf Blade
X-Scissors
False Swipe/Aerial Ace/whatever you want
Then you can catch Sandile on your way to Nimbasa level it up evolve it and teach it these moves. Dig, Crunch, Retaliate, Sand-Attack or Embargo. To beat Elesa with ease. When it evolves into Krookodile teach it Bulldoze, Crunch, Rockslide, Dragon Claw.
Krookodile
Bulldoze
Crunch
Rockslide/Stone Edge
Dragon Claw
Then beat Clay and go into Chargestone cave where you can choose between Joltik or Tynamo both Electric but joltik has Bug typing and Tynamo has Levitate ability giving it no weaknesses which is great and all but it takes alot of training whereas Joltik doesn't need much training and is fast to boot. I think you would be better off with Joltik/Galvantula. Galvantula's attacks are strong but it wont get its best attack until lv.60 Bug Buzz just use Signal Beam until then. Thunderbolt is strong but just a smidgen stronger than Discharge which has a 30 % chance to paralyze unlike Thunderbolt's 10% its your choice. Volt Switch is a very good move bc if its in on a pokemon you dont want to face Volt Switch out deal damage and get outta there. Gastro Acid is a nice move early on but replace it for Energy Ball later on you wont get the TM until you beat the E4 and go through a gaunlet of trainers.
Galvantula
Signal Beam/Bug Buzz
Discharge/Thunderbolt
Voltswitch
Gastro Acid/Energy Ball
Last pokemon is Litwick which evolves into Chandelure. Shadow Ball is self-explanitory, Flamethrower, Psychic, Confuse Ray. Good movesets and confuse Ray hits 100% for confusion, u cant argue with that.
Chandelure
Shadow Ball
Flamethrower
Psychic
Confuse Ray/Energy Ball
Your starter is the basis of your pokemon this team is terrible against rock thats where Samurott comes in. Surf, Megahorn, Grass Knot, Revenge. Replace Revenge for Ice Beam ASAP unless you cant go without it. Megahorn hits way harder than X-Scissors and its accuracy is usable. Grass Knot is for Water/Ground types.
Samurott
Surf
Megahorn
Grass Knott
Revenge/Ice Beam
Yes its weak to rock, yes Stone Edge is available for most pokemon to use but they wont get to use it they wont live long enough to use it. And there wont be any LATE game training when you catch them they can be used for the next gym you are about to face so it will gain its levels there. hope this helps.
