Gravity team

[Firebreathing Ice Cube]

Hey guys! I was thinking of making a Gravity team the other day, since it seemed so novel and interesting, and upon further research and much thinking, this is what I ended up:

Ferrothorn @ Leftovers
Iron Barbs
Impish
252 HP/48 Def/208 SpD
- Spikes
- Gravity
- Power Whip
- Thunder Wave

Clefable @ ????
Magic Guard
Bold
252 HP/156 Def/100 SpD
- Gravity
- Moonlight
- Moonblast
- Fire Blast

Dusknoir @ ?????
Pressure
Adamant
252 HP/252 Atk/4 Def
- Gravity
- Pain Split
- Earthquake
- Will o' Wisp

Garchomp @ Choice Band
Rough Skin
Jolly
4 HP/252 Atk/252 Spd
- Outrage
- Iron Head
- Stone Edge
- Earthquake

Starmie @ Life Orb
Natural Cure
Modest
4 HP/252 SpA/252 Spd
- Blizzard
- Thunder
- Recover
- Rapid Spin

Rotom-H @ Sitrus Berry
Levitate
Timid
100 HP/156 SpA/252 Spd
- Overheat
- Volt Switch
- Thunder Wave
- Will o' Wisp

Any suggestions on how to improve on this? Not that it's bad to start with, I just think there's still so much room for improvement :P I'm really stumped especially with the sweepers, which ones I should take, and the spinner. Also, I just kinda winged the EVs, so if there are specific threats I need to take note of, please tell me :) BTW I don't play on PS, just on Wi-Fi, so if you're going to suggest new Pokemon, please take into account I can't do previous gen transfers :P Take note, there are the effects under Gravity:

1) Flying-types and Pokemon w/ Levitate lose their Ground immunity and are affected by Spikes and Toxic Spikes (when usually they won't be)
2) Certain moves that make the Pokemon go airborne are disabled (Hi Jump Kick, Fly, etc.)
3) Evasion of all Pokemon is lowered by 1.67x (in effect, making the accuracy of attacks rise to 1.67x)

Use Leftovers on Ferrothorn.

Use a full physically defensive spread on Clefable, as its Defense is average. Use Leftovers as the item.

Therian Landorus makes a better user of Gravity, IMO, since it packs more offensive presence, which compensates for the fact that it's affected by Gravity itself:
-Gravity
-Earthquake
-Stone Edge
-Knock Off/U-turn/Hidden Power (Ice)
Nature: Jolly/Naive
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb

Iron Head hits non-Togekiss Fairies ever-so-slightly harder than a neutral Earthquake, so it's not worth using:
-neutral STAB Earthquake: 100 x 1.5 = 150
-2x super effective Iron Head: 80 x 2 = 160

Garchomp's Mega mixed set does a better job at wall breaking than a Choice Banded one (even if the Mega form is only used on sand teams). Choice Scarf is the better option to make Garchomp a better revenge killer:
-Outrage
-Earthquake
-Stone Edge
-Fire Blast/Dragon Claw
Nature: Naive/Jolly
EVs: 252 Atk/4 SAtk/252 Spe
Item: Choice Scarf

The lack of STAB hurts on Starmie, you know. Drop Recover for Hydro Pump; Starmie isn't meant to last long.

What's the deal with Heat Rotom's EVs? It's better physically defensive to better handle Talonflame:
-Volt Switch
-Overheat
-Will-o-Wisp/Thunder Wave
-Pain Split/Rest
Nature: Bold
EVs: 248 HP/216 Def/44 Spe
Item: Leftovers/Chesto Berry

Thanks! The EVs were just random, I though someone would suggest better ones :)) your suggestions make sense, i'll keep them in mind :D although i might be hard-pressed to find a Landorus with decent IV's around :P would you suggest anything else? i really don't have access to BW move tutors and poketransfer, that's why i might have a hard time getting a Landorus with gravity :))
