ORAS OU Mega-Gardevoir based OU team?

[Symphonic_Sage]

I'm suffering from major 6-slot syndrome right now. This is what I have so far:

Gardevoir @ Gardevoirite
Ability: Trace
EVs: 24 Def / 232 SpA / 252 Spe
Modest Nature
- Calm Mind
- Hyper Voice
- Psyshock
- Focus Blast (or perhaps Energy Ball to deal with Rotom-W?)

Bisharp @ BlackGlasses
Ability: Defiant
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Knock Off
- Sucker Punch
- Iron Head
- Pursuit/Swords Dance

Talonflame @ Choice Band
Ability: Gale Wings
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Brave Bird
- Flare Blitz
- U-turn
- Tailwind?

Keldeo @ Choice Specs
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hydro Pump
- Secret Sword
- Scald
- Icy Wind

Landorus-Therian @ Leftovers
Ability: Intimidate
EVs: 252 HP / 240 Def / 8 SpD / 8 Spe
Impish Nature
- Stealth Rock
- Earthquake
- U-turn
- Stone Edge


Excadrill @ Air Balloon

Ability: Mold Breaker

EVs: 252 Atk / 4 Def / 252 Spe

Jolly Nature

- Earthquake

- Iron Head

- Rock Slide

- Rapid Spin

I know I need a hazard remover, but I'm not happy with Excadrill: it repeats types I already have, shares weaknesses with my other pokemon, and adds nothing in terms of coverage.

Any ideas? I really want to base this around Mega-Gardevoir.

Additionally, I've never actually used Keldeo before, so I don't know what set would best complement the M-Gardevoir set.

Please follow rmt rules.
Your M-Gardevoir is cool focus blast is fine,it can ko rotrotom-w with hyper voice 2. You can also try sub cm on gardevoir.

For Bisharp I think swords dance is fine.

For talonflame try sharp beak not choice band, u can put roost on the last slot ;).

Your keldeo is good.

Lando-t is also cool.

If u don't like excadrill, u can try mandibuzz to counter other talonflames and M-pinsir or latios /latias which can protect u from thunderbolt,but it will add ghost and ice weakness,u can try skarmory 2 if u want or u can try mew (maybe).

How about trying Lati@s to deal with hazards through Defog?
The Dragon typing gives you resistance to Water, Fire, Grass and Electric. You can use it to bait in Fairies for Bisharp to deal with, or Dragons for M-Gardevoir. As well as Defog support, Lati@s can use Trick to cripple opposing 'mons by giving them a Choice Scarf. Both are able to drop powerful Draco Meteors. Finally, Latias is able to provide Healing Wish Support to bring another team mate to full.
