alrighty the team i am about to tell you will take alot of work so bear with me!
Starter:
Blaziken
sky uppercut/ hi jump kick
Flare blitz/flamethrower
Brave bird
Bulk up
my favorite fire type because he can learn flying moves, fire moves, and fighting moves
take advantage of all his types!
Salamence:
Dragon dance
Dragon claw
Fly
fireblast/draco meter (i prefer fblast)
Has great offensive stats, Dragon dance up then hit the opposition with a powerful fireblast or dragon claw
Metagross
Earthquake
meteor mash
psychic
hammer arm/iron defense
make the decision if you want this to me a attacker with solid defense to support or just straight attacker... I recomend hammer arm although i have seen iron deffense work though
now for a more d line up
Ludicollo (left overs)
Giga drain
rain dance (rain dish)
hydro pump
leech seed
i like this pokemon because of his ability and move pool! also how he is grass and water. He is a very good wall in a way. Since there is so many things that can contribute to keep him healthy. Teach him rain dance so rain dish will heal him then throw some seeds and get some health there and giga drain will also keep him healthy, then left overs... after every turn your oponnent will be screaming because you will recover all your health back! the only weakness is poision bug and flying... and if you use this strategie you will out last them any way
Now here is a little choice you have three pokemon to chose from it will change the style of your team
Wailord/Gyrados/walrein
I recomend walrein because it is all aroung stats although if you want heavy O take g-dos
or if you want another wall for some D line take Wailord for the heavy HP.
I will give you the moves for Walrein but if you want one of the others make sure they know a ice move and G-dos knows a dragon move and hydro pump and Wailord should know a ice and very powerful water moves.
Walrein:
Surf
Ice beam
Waterfall
Rain Dance
use rain dance first (if not already in affect, so your water will be extra strong and also you wont have to use it if you want for ludicollo)
Claydol Great pokemon:
Psychic
Ancient power
Earthquake
Shadow Ball
Your Team Does not really have a Special attacker which is not a big deal it just means you are alot more psychical! so don't relay on that to bail you out all though you should be fine
Claydol :Special Defense (Defense)
Wailmer: All around
Blaziken: Mixed attacker with nice speed
Ludicolo: Wall style recoverer, with nice mixed stats
Salamence: Sweeper (heavy attacker)
Metagross: Attack and Deffense pro!
