Help build team?

[Orocket]

Hey guys so far I know I'm going to use these two:

Special Sweeper
Scrappy (Gengar)
Ability: Levitate
EVs: 252 SAtk/ 252 Spd/ 4 SDef
Timid Nature
-Shadow Ball
-Thunderbolt
-Dazzling Gleam
-Sludge Bomb

Physical Sweeper
Blaze (Blaziken)
Ability: Speed Boost
EVs: 252 Atk/ 252 Spd/ 4 Def
Adament Nature
-Blaze Kick
-Brave Bird
-Protect
-Brick Break

I'm really only trying to look for a third team member because online you only put in three. Any suggestions?

I don't think Gengar needs Dazzling Gleam, tbh. It already hits Dragons hard with Shadow Ball:
-Shadow Ball
-Sludge Bomb
-Substitute/Protect
-Focus Blast/Hidden Power (Fire)
Nature: Timid
EVs: 4 Def/252 SAtk/252 Spe
Item: Black Sludge/Life Orb

or
-Shadow Ball
-Sludge Bomb
-Focus Blast
-Thunderbolt/Hidden Power (Ice/Fire)
Nature: Timid
EVs: 4 Def/252 SAtk/252 Spe
Item: Choice Scarf

Brave Bird doesn't have good coverage on Blaziken. Blaziken also has a stronger Fighting STAB in High Jump Kick:
-Swords Dance/Baton Pass
-Flare Blitz
-High Jump Kick
-Protect/Baton Pass
Nature: Adamant/Jolly
EVs: 4 HP/252 Atk/252 Spe
Item: Life Orb/Leftovers/Blazikenite
Ability: Speed Boost

Hazard setters like Ferrothorn work nicely on the team to help ensure OHKOs/2HKOs like Skarmory and Ferrothorn:

Ferrothorn:
-Spikes/Stealth Rock
-Leech Seed/Thunder Wave
-Power Whip/Gyro Ball
-Stealth Rock/Gyro Ball/Protect
Nature: Relaxed
EVs: 252 HP/76 Def/180 SDef or 252 HP/200 Def/56 SDef
Item: Leftovers
Ability: Iron Barbs

Skarmory:
-Spikes
-Whirlwind
-Roost
-Brave Bird/Steel Wing/Taunt
Nature: Impish/Careful
EVs: 224 HP/252 Def/32 SDef or 224 HP/32 Def/252 SDef
Item: Leftovers/Shed Shell
Ability: Sturdy
