[ORAS] OU Need help!!!

Building a team for OU but I have no ide about a 6th member. I don't want legends or rotom :P also advice needed on item for togekiss.

Team:

Sceptile (M) @ Sceptilite
Ability: Overgrow
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Giga Drain

- Focus Blast
- Substitute

Mienshao (F) @ Life Orb

EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature

- Knock Off

Togekiss (M)
Ability: Serene Grace
EVs: 248 HP / 8 SpA / 252 SpD
Calm Nature
- Nasty Plot

Goodra @ Assault Vest
Ability: Sap Sipper
EVs: 240 HP / 252 SpA / 16 Spe
Modest Nature

Vaporeon @ Leftovers

On Goodra, Muddy Water and Earthquake are more reliable ways to hit Heatran than Focus Blast. Sludge Wave or Thunderbolt should be used to hit Fairies and bulky Waters, respectively. Fire Blast is better over Flamethrower, as it has good power while having acceptable accuracy:
-Draco Meteor/Dragon Pulse
-Fire Blast
-Sludge Wave/Thunderbolt
-Muddy Water/Earthquake
Nature: Modest
EVs: 240 HP/252 SAtk/16 Spe
Item: Assault Vest
Ability: Sap Sipper

This team is rather susceptible to Talonflame. I don't get why you don't want Wash Rotom, as it's one of Talonflame's biggest counters. Well, there's Rhyperior as an alternative, I guess:
-Stealth Rock
-Earthquake
-Stone Edge/Rock Blast
-Ice Punch/Toxic
Nature: Adamant
EVs: 212 HP/44 Atk/252 Def
Item: Leftovers
Ability: Solid Rock
