Lead pokemon because of its deffensive abilities, having lots of resistances but a good attacker also with the stab moves when possible or earthquake agaanst a pokemon that resist psychic or steel or is weak against earthquake

Offensive against most pokemon with a calm minded STAB move she can ko many pokemons easily knows thunderbolt to use against pokemon that resist psychic moves

Blaziken @Charcoal

80 HP / 232 Atk / 196 Spe
Blaze Kick
Don't know if sky uppercut or double kick

same as gardevoir but with physical attacks this time also his great speed let it outmatch most pokemons

Flygon @Soft sand
Mild Nature +spa -def
80 HP / 224 Atk / 16 Def / 8 SpD / 180 Spe

Useful against pokemon with high defense also teamed with skarmory's spikes so the oponent has to decide if suffer the damage from spikes or face an earthquake with low deffense because of screech

Wobbufet @leftovers
gentle nature +spd – def
4 HP / 252 Def / 252 SpD
Counter
Mirror coat
Endure
Safeguard

He is used second to KO all the pokemons it can ressist befoer being KOed

Skarmory @king rock
Impish nature +def -SPa
EV 252 HP / 60 Atk / 184 Def / 12 Spe
Steel wing
Roar
Spikes
Agility

To set the spikes and to resist physical hits and most of special hits, it's in my team as a support

It's a simple all around team with metagross and skarmory as walls and blaziken and gardevoir as an offensive force both using cam mind and bulk up to rise their offensive even more, wobbuffet to counter strong pokemon and flygon when facing thunder pokemon or ground moves as well as pokemon with high defense
Skarmory is also used to set spikes and roar pokemons into the spikes

thank you in advance
