You could always give Latias HP/Def EVs + rest/sleeptalk and use it in a similar manner as Suicune if you want to keep the same pokes. Otherwise Starmie is best replaced. Jolteon already has fast T-bolts, Gyara has your DD(speed) and Water/Ice coverage. and Suicune, in particular rest/talk variants can absorb status just as well as natural cure and still gives you your special water coverage.

Also any other choice would give 3 electric weaknesses, quite crippling if Jotleon and/or Latias is KO'd or removed for the team.

Regirock doesn't take electric attacks super well since they're almost all special (unless you get the sandstorm boost), And Registeel can take em but unless it has a lot in HP/S.def they will wear him decently.

One downside to Scizor is that it's become too popular, thus it's sweeping power is weakened as every team makes sure to have multiple counters for SD+Bullet punch as well as odd placed fire moves to fry him. It's still good, just don't play him too early unless necessary as you opponent is likely to keep his check/counter alive.

Gyarados is actually among to top OU pokes as well, that electric weakness is bad but can easily be used to bring a ground or Jolteon/Electrivire. (Which you have going :p)

I would go with starmie, and you also have a good moveset for him.

Why should I get rid of Starmie? Just saying to get rid of him doesn't help me much, I need reasons too.

well really your not helping at all a good pokemon [and you explained why it's a good pokemon also] is what you want to get rid of is just stupid
and in my oppinion there are better shields then suicune and w/gyrados and latios you have too many weaknesses to electric and not much to counter it my shield is cresselia why not give her a whirl or even registeel could do well

ok a battle scenario for you i will use marriland's [i presume you've heard of him] team

okay go metagross
go salamance
you swap out for gyarados because you know he'll use harthquake or d dance
he uses equake
you go dancy pants as he switches to electrivire
you think can i out speed it maybe not and switch to jolteon who takes the thunderpunch and now what do you do

if you swapped to cresselia he'd swap to something like blissey and it gets hit by psychic or whatever now people know that cresselia will have ice beam energy ball shadow ball moonlight psychic etc in its arsenal but if you were creative with the cresselia you could have hidden power fighting thunder wave toxic lunar dance reflect light screen safeguard etc for exmple this cresselia [against a blissy it wont be much trouble to you]

psychic
thunder wave
hidden power fighting
moonlight

it could be interesting with df and sp df evs and maybe a few sp a evs

just think about it but i would drop starmie for something else as well maybe for cresselia?

also could you post metagrosses moves etc and items thx

well your gyrados is fast because mines lv 94 and its speed is 198

then anyway he'll use earthquake and you faint then you're thinking what to do

but it's good that your gyrados is fast

if you go to youtube and type in marriland you'll find him his battles are near the bottem of his video stockpile
