Help improve my team? (RMT)

[X-Scissor]

Okay here is my team:

Dusknoir@leftovers
252 HP / 76 Def / 180 SpD
careful
-will o wisp
-thudnerpunch
-pain split
-shadow sneak
Pretty much the standard smogon set here. This guy can take hits, and pain split is a killer. Need I say more?


Blissey@leftovers
bold
148 HP / 252 Def / 108 SpA

-thunder wave
-ice beam
-softboiled
-seismic toss

I honestly don't think I need to talk much about a Blissey
however, this one is a bit different, I like to spread status effects while stalling


Gliscor@leftovers
impish
252 HP / 4 Atk / 252 Def
-EQ
-Stealth Rock
-Ice Fang
-Roost

Another pokemon meant to take hits, and a heracross counter

Metagross@leftovers
brave
252 atk 252 def 4 hp
-Bullet Punch
-Meteor Mash
-EQ
-Zen Headbutt

This guy is a good physical wall and is guaranteed to take something down before he goes down, however, I don't really know what else to do with him

Dragonite@life orb
lonely
252 speed 252 atk 4 hp
-EQ
-DD
-Outrage
-Fire Blast

This is simple. Set up DD and sweep with Outrage, something Dragonite is regarded well for
I have a lonely nature instead of adamant, because i want to boost sp. atk a bit

Gengar@life orb
timid
252 SpA 252 speed 4 hp
-Thunderbolt
-Focus Blast
-Hypnosis
-Shadow Ball
I need a special sweeper...here he is.




Apart from these Pokemon, I don't know what I could do to make it better. Is there something lacking? or rather, am I using too many defensive Pokemon?
What could I do to make the team better?
