Hey everyone, I'd just like to say that I'm just starting to get into competitive Pokemon and this is the first team I've made so yeah, I'm a newb at this sort of thing. Now, without further adieu... here is the team:

Ferrothorn w/ Leftovers
Nature: Relaxed
Ability: Iron Barbs
EVs: 252 HP, 88 DEF, 168 SpDef
Moves:
Spikes
Stealth Rocks
Leech Seed
Power Whip
Ferrothorn is the Pokemon that sets up entry hazards as well as walls opposing Pokemon. Can also regenerate HP with Leech Seed. Now, I want to add protect into the moveset but am unsure if it is needed.

Heatran w/Leftovers
Nature: Calm
Ability: Flash Fire
EVs: 252 HP, 252 SpDef, 4 Spe
Moves:
Lava Plume
Roar
Protect
Toxic
Heatran is there to wall many things as well as get residual damage going with Roar and Toxic. Can also stal with Protect to get HP back with Leftovers and get more Toxic damage in. Air Balloon could be another Item I could use instead of Leftovers. Suggestions?

Gliscor w/Toxic Orb
Nature: Impish
Ability: Poison Heal
EVs: 252 HP, 184 Def, 72 Spe
Moves:
Substitute
Protect
Roost
Earthquake
Gliscor is another one of my walls as well as a stall Pokemon. Stalls out after Heatran has Toxic'd a Pokemon and Gliscor just Subs and Roosts while healing with its ability.

Starmie w/Life Orb
Nature: Timid
Ability: Natural Cure
EVs: 252 SpAtk, 252 Spe, 4 SpDef
Moves:
Surf
Ice Beam
Recover
Rapid Spin
Starmie is the Spinner for this team. With Dragonite as the Offensive sweeper I need a way to get rid of Stealth Rocks. Starmie also acts as a Special Sweeper if need be. Some moves could be changed though. Surf and Recover could be switched out for moves like Hydro Pump or Thunderbolt.

Dragonite w/Leftovers
Nature: Adamant
Ability: Multiscale
EVs: 252 Atk, 252 Spe, 4 HP
Moves:
Outrage
Roost
Dragon Dance
Earthquake
This Dragonite is the Physical Sweeper of the team. I can use the Banded Dragonite instead of the DragonDance one. Which one would be better suited for the team I have currently?

Genesect w/Choice Scarf
Nature: Mild
Ability: Download
EVs: 252 SpAtk, 252 Spe, 4 HP
Moves:
U-Turn
Flamethrower
Ice Beam
Thunderbolt
The Special Sweeper of the team as well as the Revenge killer in some cases. Has great type coverage with the moves it has and can swiftly kill with the Choice Scarf.
