Spiritomb would work better like this:
Spiritomb@leftovers
Bold
Will-o-wisp
Calm mind
Pain Split
Shadow Ball/Dark Pulse

Shadow ball gets you walled by normals, while dark pulse is quad-resisted by heracross, who will love coming in on a will-o-wisp. There are also other sets for spiritomb, this one just happens to be my favorite.

Why in the world would you give breloom an iron ball? Even for fling, it's too much of a unitasker. Try a sporepunch set like this:

Breloom@toxic orb
Adamant (poison heal trait)
Spore
Focus Punch
Substitute/Stone Edge
Seed Bomb

Spore someone, and then either substitute or focus punch on the switch. Stone edge will give you another attacking move (one that doesn't get walled by flyers), while substitute grants you a bit of a shield. Mach punch can also be used if you lead with this to take out weavile.

Try a standard paraflinchhaxx togekiss:
Togekiss@leftovers
Modest
Air Slash
Aura Sphere
Thunder Wave
Roost

This set is evil.

Hippowdon really isn't meshing with the team well. If you want to read up on it a bit, read the sticky about tyranitar. Otherwise, try a curse set.

Lanturn can't sweep. With the set you gave, you might as well just use starmie, who will be stronger and faster at it. Go with a calm nature and use thunder wave over signal beam. However, I do suggest replacing lanturn with a better bulky water, such as suicune, milotic, or gyarados. Yes, gyarados can be bulky. Starmie is also worth a thought.

If you want to sweep with espeon, go with this:
Espeon@leftovers
Timid
Calm Mind
Psychic
Shadow Ball
Grass Knot

You can also try baton passing. If you can get off two or three calm minds onto togekiss, you're pretty much set for the game, although you might want to consider a bold nature on togekiss if you think you can pull this off.
