Helping a friend make a decent team

Im trying to help my friend make a team. (even with as much as i pushed Salamence, she turned the idea down *Sad Panda*)

her favorite pokemon is Cloyster so this team needs to have one, and theres also the fact that she hates Dragon types and ghost types (or anything "creepy" looking). she does Doubles alot (like myself) so some moves that Hit both opponents may trump raw power.

Cloyster@White herb@Skill link
Jolly
EVs: Spd 252, Atk 252 Hp 6
1 Icicle spear
2 Rock Blast
3 Razor shell
4 Shell smash

She wanted me to help her make it so i went with what smogon said.
(I will never understand why she considers this beast "cute")

Chansey@eviolite@natural cure
EVs: Hp 252, Def 252, 4 SpDef
1 Counter
2 Soft-boiled
3 Seismic toss
4 Thunder wave

She wanted a "cute" pokemon, and Blissey wasnt cute enough for her

Conkeldurr@Choice band@Guts
EVs: Atk 252, Def 252, Hp 6
1 Mach punch
2 Stone edge
3 Superpower
4 Wide gaurd

I pushed Conkeldurr because he outclasses Lucario, (from her previous team) so after a fit Of "hes ugly" I finally convinced her to go with Conkeldurr

Espeon@Choice specs@ Synchronize
EVs: SpAtk 252, Spd 252, Hp 6
1 Psychic
2 Hidden power fighting
3 Signal beam
4 shadow ball

She likes "cute" pokemon, and this was her favorite Eevee-loution (I know your all thinking "how could Vaporeon not be her Favorite?!?!", I know cause im wondering that too.)

Jirachi@Choice scarf@Serene grace
EVs: Atk 252, Spd 252, Def 6
1 iron head
2 U-turn
3 fire punch
4 Drain punch

He is the epitome of cute

Ninetails@Life orb@Flash fire
EVs: no clue since im pretty sure shes had this Ninetails since Sapphire, but im pretty sure its mostly SpAtk and Spd
1 Heat Wave
2 Hypnosis
3 Dream eater
4 Will-o-wisp

Her Second favorite pokemon. Please help me make a better one since Dream eater is useless.

Okay first im going to say im not experienced at double battles so if i say something stupid just ingnor it. Okay you have a slight weakness to fighting, electric and ground. Fighting hits two members for super effective and only one resists, electric hits one for super effective and no resist and finally ground hit 2 members for super effective and you have no resist/immunitys (Ground is especially bad considering how common earthquake is).

Ill post all sets at the end. First id suggest changing Espeon set to a duel screen set with its new ability magic bounce. This seem like it would work in double battles as screens would help out the team and magic bounce is just a great ability.
Next id change Conkeldurrs set as choice band locks you in a move when you can get that same boost without locking yourself into into a move, ill explain below.
That Ninetales set isnt good. Honestly if you want to make ninetales a good pokemon give it drought, although that might clash with cloyseter.
Okay now for replacements, id suggest replacing chansey. Chansey is a fantastic wall/supporter but honestly with physicall attackers around like terrakion it wont do as well. Id suggest replacing it with a supporter like Whimsicott or Tornadus. Also Zapdos would do well. Anyway ill just suggest a few pokemon with their sets and you can decide if you like them or not.

Changes:

Some possible replacments:

Trick Room/Protect/Memento
252HP/252Speed/4Def



Jolly@Flying Gem@Prankster
Tailwind

First Id replace Chansey, Then Ninetales or Jirachi. If she wont replace one of the above just replace any pokemon thats not fitting the team well.

the Espeon looks good.

The Conkeldurr seems good but why detect? wide guard will let her protect her teammate as well in case of the rockslides or earthquakes that i see so much of.

Ninetails. lets face it, A Ninetails wont work well with her team. A better pokemon is needed.

Whimsicott is "cute enough" to make it on the team and the helping hand looks great for doubles, but i think light screen will be better then protect for if she needs some priority SpDef for Cloyster or itself.

Zapdos. i think giving up heat wave is a good trade for lightning rod. as Cloyster will appreciate the Anti-thunder/bolt support.(now to convince her that a big spiky yellow bird is cuter then Ninetails)
PS whats a good replacement for heatwave?

Tornadus. she said "that's not happening."

So:
Cloyster(set up and sweep)
Espeon(support/Attacker)
Whimsicott(support)
Jirachi(his flinching prowess kept him on the team)
Zapdos(Support/Attacker)

now we're short a pokemon..... any ideas for the last slot since Chansey got shut down?

The reason i didnt put wide guard on Conkeldurr is because i dont know what it does. That just shoes my experience of double battles so you know best their. Note that Lightning rod Zapdos is unreleased. Wile lighning rod may seem its a good trade off, trust me its not Heatwave is awesome. But if you like lightning rod i guess some replacments are Volt Swith, Roost, light screen, rain dance, toxic, thunder wave and Sub.
Also you say your one short but what happened to conkeldurr? haha

oops. forgot bout Conkeldurr. And I forgot bout Lightning rod not being out yet. I just took a look at Zapdos's page on a few sites and saw Its DW ability. Il have her take a look and let you all know what she says.

Okay. Im sure she will find Whimsicott cute enough. If you confinced her that conkeldurr was usable im sure you can with zapdos.

haha. k the team now is:

Cloyster(lead)
Skill link@white herb
1 Icicle spear
2 Rock blast
3 Razor shell
4 Shell smash
(Paired with a white herb and Light screen support she can set up while staying defensive)

Whimsicott(mostly here to give Cloyster some spdef support)
Prankster@focus sash
1 Light screen
2 tailwind
3 encore
4 Leech seed
(Pranksters are awesome)

Conkeldurr(hits hard)
guts@flame orb
1 Drain punch
2 rock slide
3 Mach punch
4 Wide guard
(pairs well with Espeon cause if they target Espeon then he can storm them, and if they target him, Espeon will have some time to set up)

Espeon(anti entry hazards/dual screens)
Magic bounce@light clay
1 Reflect
2 Light screen
3 Psychic
4 Hidden power (fighting)
(Just a supporter/ Anti entry hazard pokemon. she pairs well with everyone other than Whimsicott)

Zapdos(needed some form of anti water)
Pressure@fire gem
1 thunderbolt
2 Heatwave
3 Hidden power(grass)
4 detect
(Hits grass types and water types very hard. coverage is nice and pressure will help stall a few 8 pp moves)

Jirachi(im going to need some help here cause i looked at her Jirachi and its modest......and that wont do on a physical Jirachi)
Serene Grace@kings rock
1 Iron head
2 drain punch
3 fire punch
4 Body-slam
(cute, yet can flinch the enemy to death. pairs well with Espeon, Whimsicott, and Zapdos due to Screens making him a tank and He covers some of the rock types that would destroy Zapdos)
