Story team

Hi! I want to try play through the game with a new team and wanted some opionions. I’m going for a hit hard and hit fast team.

Lucario w/mega. Jolly. 252 attack. 252 speed. 4 hp. Close combat, bullet punch, EQ, ice punch

Garchomp w/rocky helmet. Rough skin. Jolly. 252 attack. 252 speed. 4 hp Outrage, EQ, stone edge, poison jab

Ruin D. Metagross w/mega. Rock head. Jolly. 252 attack. 252 speed. 4 hp. Rock head, wood hammer, EQ, crystal rush

Gardevoir w/?? Synchronize. Timid. 252 s. attack. 252 speed. 4 hp. Moonblast, thunderbolt, shadow ball, psyshock

Greninja w/?? Protean. Timid. 252 s. attack. 252 speed. 4 hp. Surf, dark pulse, ice beam, extrasensory

Chandelure w/?? Infiltrator. Timid. 252 s. attack. 252 speed. 4 hp. Shadow ball, flamethrower, energy ball, psychic

As you can see, I need some help picking items. Any other comments are also appreciated!

My Boy Greninja For Sure needs to hold a Life Orb. Gardevoir Choice Specs or life orb works too. and chandelure same options as gardevoir since you want to hit hard and you have max speed already.
