[X] My Assistant

[Wonderbread]

So, I'm somewhat new to competitive battling, and I've got a team that I'll post in a second. Some of it works, but I'm not winning as often as I should be. I'm wondering if any of my team can be improved or even replaced. Here it is:

Aerodactyl @ Focus Sash
Pressure
EVs: 255 Atk / 255 Spd
Jolly Nature (+Spd, -SAtk)
- Earthquake
- Stealth Rock
- Taunt
- Stone Edge

Volcarona @ Focus Sash
Flame Body
EVs: 255 SAtk / 8 SDef / 244 Spd
Modest Nature (+SAtk, -Atk)
- Quiver Dance
- Flame Dance
- Bug Buzz
- Hidden Power [Ground]

Breloom @ Toxic Orb
Poison Heal
EVs: 255 Atk / 255 Spd
Adamant Nature (+Atk, -SAtk)
- Mach Punch
- Seed Bomb
- Swords Dance
- Stone Edge

Exeggutor @ Leftovers
Chlorophyll
EVs: 255 SAtk / 255 Spd
Modest Nature (+SAtk, -Atk)
- Psychic
- Leaf Storm
- Energy Ball
- Sludge Bomb

Conkeldurr @ Flame Orb
Guts
EVs: 255 Atk / 255 Def
Adamant Nature (+Atk, -SAtk)
- Bulk Up
- Drain Punch
- Mach Punch
- Stone Edge

Drapion @ Life Orb
Sniper
EVs: 255 Atk / 255 Spd
Adamant Nature (+Atk, -SAtk)
- Hidden Power [Ice]
- Swords Dance
- Crunch
- Night Slash

Aerodactyl and Volcarona work great, Exeggutor is good too but I think he needs to get rid of Leaf Storm, and Conkeldurr/Breloom have their moments, but I think I can keep one but lose the other. As for Drapion, his only real use is countering Dragons, other than that he's not very useful. What do you think?

With a suicide lead, you might want something that has the ability to block rapid spin. Otherwise, it's a waste of a slot. I'd suggest Jellicent or Chandelure, which could replace either Exeggutor or Volcarona. Exeggutor is too slow and Volcarona takes 50% damage every time it switches in due to Stealth Rock.

Breloom should have Spore.

You also might want to invest in a Steel-type (Empoleon) to handle dragons. As of right now, Hydreigon does a pretty good job of wreaking havoc. It usually carries Fire Blast, though, so even better would be a flat-out special wall like Porygon-2 or Snorlax.

If you want a flat-out special wall, you might take a look at Eviolite Chansey or the run-of-the-mill Blissey; the former seems to have greater bulk despite losing the Leftovers health gain. Porygon-2 is a good suggestion for the same reason: good bulk as a wall. I'd ditch Drapion for any of the aforementioned suggestions.

I also feel like Conkeldurr and Breloom are filling the same roles on your team and are therefore redundant, especially since you're running Breloom more like a standard physical sweeper and less like...well, Breloom. I'd consider swapping one or the other for a supporter (either another Spiker or a Spinner/Spinblocker).
