First Team.

[~p 0 k e y]

Azelf @ Focus Sash
Ability: Levitate
Nature: Naive
EVs: 4 Atk, 252 Spe, 252 SpA

-Taunt
-Psychic
-Stealth Rock
-Explosion

I like Azelf as my lead, as Taunt and its high speed shuts down most common leads as they try to set up entry hazards.

Salamence @ Life Orb
Ability: Intimidate
Nature: Naive
EVs: 232 Atk, 24 SpA, 252 Spe

-Dragon Dance
-Earthquake
-Roost
-Outrage

I used to prefer Lucario as it pretty much rapes Blissey, but I don't like Lucario's many weaknesses against common moves.

Skarmory @ Leftovers
Ability: Keen Eye
Nature: Impish
EVs: 252 HP, 64 Atk, 176 Def, 16 Spe

-Brave Bird
-Spikes
-Roost
-Whirlwind

Typical Skarmory. Add layers of Spikes to Stealth Rock, Whirlwind away against threats or to add damage, Roost when unhealthy, Brave Bird to get some offense.

Rotom-H @ Leftovers
Ability: Levitate
Nature: Bold
EVs: 252 HP, 168 Def, 88 Spe

-Thunderbolt
-Will-o-Wisp
-Overheat
-Shadow Ball

The Spin blocking champ. I personally prefer burning opponents over poisoning them, as while it doesn't do as much damage, it still halves their attack.

Vaporeon @ Leftovers
Ability: Water Absorb
Nature: Bold
EVs: 188 HP, 252 Def, 68 Spe

-Surf
-Wish
-Protect
-Ice Beam

I prefer Wishporeon over WishBliss anyday.

Tyranitar @ Leftovers
Ability: Sand Stream
Nature: Quiet
EVs: 252 HP, 52 Atk, 176 SpA, 28 Spe

-Substitute
-Focus Punch
-Dark Pulse
-Thunderbolt

Since Azelf has Stealth Rock, Hippowdon was pretty much out of the question. So I came to a typical Tyraniboah. Like Hippowdon, it has Sand Stream, and it can do just as, if not more, damage than your typical Hippowdon.

This is an Ok team.
I would change your random 32 SpA into attack.
I also think there are not enough Attackers on your team.
There isnt that much details describing anything, so....

DD mence usually does't have roost.

Having a heal move is always nice to have, especially with Life Orb.

 

[CreepacisT]

nice semistall you got going there.
Let's see...
Azelf is fine.
Mence has spA evs but no special attacks. Make the spread 252 Atk 252 Spe 4 HP He also doesn't necessarily need roost since you have a cleric so that can be changed to another move.
Skarm is fine.
So is Rotom.
Move those speed EVs on Vappy to HP an SpA: 252 HP 252 Def 4 SpA. He really has no need to outspeed anything.
tyraniboah is actually perfect for your semistall team.
