Nice team, but it lacks a good wall or tank. Also, Excadrill is in Ubers. Electivire is in RU and is pretty good, but there are other options that are bulkier like Lanturn or if you want a fast, special sweeper, Jolteon is a good option. Rotom-Wash is also a solid choice. Your team has very good synergy. A Ground-type Rapid Spinner is Donphan. He has solid defense and good Attack and HP. Other options for spinners are Tentacruel and Starmie. Here are some reviews for other team members and changes you could make. These changes are not necessary, but if my humble opinion could help you with your team, that would be great.
Rotom-Wash@Leftovers
Ability: Levitate 252SpA/4Def/252SpD
Nature: Bold (+Def -Atk)
Moves: Volt Switch
Hydro Pump
Pain Split
Will-o-Wisp
Electivire is fine, but Rotom-Wash could be slightly
better at tanking through the other team and provides
the defensiveness you need and the attacking powers
you seem to like. Will-o-Wisp can stop sweepers, and
everything else is for tanking.
Donphan@Leftovers
Ability: Sturdy 252SpD/100HP/88Def/68Atk
Nature: Careful (+SpD -SpA)
Moves:Rapid Spin
Stealth Rock
Ice Shard
Earthquake
You know it, I know it, it's the standard Donphan set,
but with a twist in the EV spread. It's a great physical
Wall, but that's so predictable, so I made it good at
SpD, too.
Alakazam@Life Orb/Focus Sash
Ability: Magic Guard 252SpD/128SpA/128Spe
Nature: Timid (+Spe -Atk)
Moves: Psyshock
Signal Beam
Shadow Ball
Substitute
This is a pretty good Alakazam set, you can either sweep
or hide behind a Sub. Most moves are coverage, but Psyshock
is so that you can KO Blissey, which can easily Wall your
team.
Everything else is great, so I hope I helped your team.
