I'm not that good with anything other than Flying types, but you might consider a Sub Punch Tyranitar.

Tyranitar @ Leftovers
Substitute
Focus Punch
Thunderbolt/Rock Slide
Crunch/Earthquake

Houndoom @ Focus Band
Fire Blast
Crunch
Sludge Bomb
Shadow Ball/Taunt

might work for your Houndoom.

Sharpedo @ Focus Band
Crunch
Surf
Ice Beam/Taunt
Earthquake

sounds better-if you have a dark team, use dark moves

Cacturne @ Leftovers
Leech Seed
Giga Drain
Faint Attack
Sludge Bomb/Toxic

would probably do a bit better.

I have no clue about your Shiftry, I've never used him.

Why do you have Toxic AND Poison Fang on Mightyena? That's 2 poison moves. Nuh-uh.

Mightyena @ I dunno, probably focus band
Crunch
Shadow Ball
Taunt
Swagger/?

That should work a bit better.

[Capuchin_monkey]

replace that cacturne with a umbreon!

[SuperRyoko2k3]

replace mightyena with absol(c00lest,fastest and better than mightyena)

Few changes.

Tyranitar @ Leftovers
252 HP ev's are important-make sure you have that. spread the rest how you want.
give him an adamant nature
Substitute/Focus Punch/Thunderbolt/Crunch

OR

Tyranitar @ Leftovers
spread ev's however
Adamant
Dragon Dance/Earthquake/Rock Slide/Aerial Ace(for fighters-fighting types slaughter tyranitar)

Houndoom @ Leftovers
spread EV's how ya want.
Modest nature
Fire Blast/Sunny Day/Solarbeam/Taunt

Sharpedo @ Leftovers
a special sharpedo sounds good to me-modest nature
Surf/Crunch/Ice Beam/Taunt

Cacturne @ Leftovers
Modest.
Hmmm... Giga Drain/Leech Seed/Faint Attack/Toxic sounds aight to me-dunno

Shiftry @ Leftovers
Still, NO CLUE =\

Mightyena, neh, but I dunno anything else...

Mightyena @ Leftovers
Adamant =\ I guess
No clue =\ Crunch though of course.

I wouldn't ever run more than 2 of one type in a team. I've got Hitmonlee/Heracross/Alakazam/Metagross/Aerodactyl/Houndoom.
