Rate my competitive team:
cloyster with choice band, razor shell icicle shard rock blast and toxic spikes

Basicly a physichal wall with a great ability to sweep

Zoroark with life orb nasty plot dark pulse flamethrower and hp psychic

Special sweeper, hp psychic gets to deal with fighting pokemon that are zoroarks main threat.

Infernape with expert belt flare blitz, u-turn, mach punch and close combat

typical physical sweeper, mach punch allows me to hit first which is very important sometimes and u-turn lets me hit and switch

salamence - choice band fire fang crunch outrage earthquake

another physychal sweeper,

Jellicent with leftovers, shadow ball will-o-wisp recover and taunt

a staller with will o wisp that causes burn damage plus the taunt and recover help him in keeping him alive

Magnezone leftovers magnet rise, thunderbolt flash cannon, volt switch and thunder wave
