Efficient Team?

[animecrzy]

This is my planned team for competitive battle:

252 HP/252 SAt/6 Spd
-Ice Beam
-Shadow Ball
-Roar
-HP Fire/Fighting

Electivire @ Leftovers
Naughty Nature (+Att,-SDf)
252 HP/252 Att/6 Spd
-Fire Punch
-Thunder Punch
-Earthquake
-???

Shuckle @ Leftovers
Bold Nature (+Def, -Atk)
252 HP/126 Def/SDf /6 Spd
-Toxic
-Rest
-Sleep Talk
-Power Trick

Driftblim @ Leftovers
Ability: Aftermath
Timid Nature (+Spd,-Atk)
252 HP/200 Spd/56 Sp Atk
-Thunderbolt/Dream Eater
-Hypnosis
-Substitute
-Baton Pass

Spiritomb @ Leftovers
Sassy Nature (+SDf,-Spd)
252 HP/130 Def/126 SDf
-Will-o-Wisp/Toxic

-Pain Split
-Dark Pulse/Pursuit

Blissey @ Leftovers
??? Nature

As you can see, basically the entire team is focused around defense, with minor exception to Glaceon and Electrivire, is my focus on defense going to impair my teams efficiency in combat?

When in Team Builder, go to File, and then Export to Text, and your Blissey must have a nature.
