ORAS OU Step one of many to make this team work.

[Bakery300]

Hello I'm Bakery300 and I thought I'd try my had at singles and this team has been working so far. I would like some advice though on how to improve this team. The Pokemon listed I do not plan on changing, but if necessary I will.

Slowbro @ Sitrus Berry
Ability: Regenerator
EVs: 248 HP / 252 Def / 8 SpA
Bold Nature

- Belch
- Flamethrower
- Scald
- Slack Off

I wanted to use Slowbro because for a little while now I've wanted a Pokemon that could learn Belch on my team and Slowbro seemed to work best for more than one reason. First, Slowbro can take a hit and keep going and with belch it just becomes a nice fairy counterer. Second, having access to flamethrower I took the opportunity to eliminate the chance of a grass type 2HKOing me. Third, Slack off is here as a typical restoration move for later on in the battle. Lastly, Scald the burning S.T.A.B. bonus move as back up. So that's about it on it.

Serperior @ Leftovers
Ability: Contrary
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature

- Leaf Storm
- Dragon Pulse
- Giga Drain
- Glare

I've wanted to use the HA Serperior for a while ever sense i knew it was going to be legitly released. So Leaf Storm is to max my Spec Atk within three turns or such (depending on stat lowering effects). Dragon Pulse is to counter my 'Glaring' Dragon weakness. Giga Drain is to help restore my HP back to normal. Glare is there as support and paralysis. The leftovers are here to help heal overtime.

Garchomp @ Rocky Helmet
Ability: Rough Skin
EVs: 252 Atk / 4 SpD / 252 Spe

Jolly Nature
- Earthquake
- Dual Chop
- Iron Head
- Swords Dance

This Garchomp is here as a physical wall, and because this is the one I've been wanting to use to annoy my friend via Rocky Helmet + Rough Skin. The Swords Dance is there for obvious reasons, as to raise my attack. Dual Chop is there as a multi hit Dragon type move. Earthquake is there as a powerful S.T.A.B. move. Also Iron Head is there as a counter to fairy types I might encounter.

Heracross @ Heracronite
Ability: Moxie
EVs: 248 HP / 252 Atk /8 SpD
Adamant Nature

- Bullet Seed
- Megahorn
- Rock Blast
- Reversal/Close Combat

The idea here is to boost my attack with moxie and follow up with Mega skill link bullet seed and rock blast. But to also I can use CC as OP move or reversal as a backup revenge move. Mega horn is there as a move to use pre-mega evolved to do major S.T.A.B. damage.


Espeon @ Light Clay
Ability: Magic Bounce
EVs: 248 HP / 8 SpD / 252 Spe
Timid Nature

- Reflect
- Pyshock/ Light Screen
- Baton Pass
- Calm Mind

Made as a set up Pokemon, it sends back wil-o-wisp, rocks, spikes, ect. Light clay used to hold up my reflect/ light scren. Refect, light screen, and calm mind are used as set up while I baton pass afterwards. The only concern is not having an offensive move hence the ross up between the two moves. Any changes I'm open to on this mons move set.


Heatran @ Choice Scarf
Ability: Flash Fire
EVs: 248 SpA / 4 SpD / 252 Spe
Timid Nature

- Flash Cannon
- Lava Plume
- Earth Power
- Dragon Pulse

Here we have a grade A sweeper! Lol. In all seriousness choice scarf Heatran works well with my teams weakness to Mega Altairia. Having flash cannon covers Mega form. Dragon pulse covers normal. Lava plume is a S.T.A.B. attack that is powerful. Earth Power in all honesty is there for no particular reason, so if u have a better suggestion I open to ideas.

So that's what I haVe give me ur thoughts.

Cool team but I would replace toxic/thunder wave with Belch on Slowbro as blech just doesn't really make sense. Like what are trying to hit with blech. Also leftover as instead of sitrus berry as leftover is important to prevent some 2HKO and is general a better item. On garchomp iron should be replace on stone edge to beat to Togekiss or Fire fang Skarmory and Ferrothorn. Also Dragon claw has the same power but better accuracy. Heracross should be running max speed pin missle over megahorn and definitely Close combat. Reveal isn't nearly good. I also think Heatran should be changed to a more Special defensive spread with stealth rocks.

While dual chop is a fun sub breaker, you can certainly make better use of a dragon move, seeing as Dual chop has 80 base attack for both hits and has a 90% accuracy for it. Much better moves to replace would include Outrage (locked 2-3 move with 120 base -100% acurracy- power resulting in confusion afterwards) or Dragon Claw(Simple but effective 80 base power attack with 100% accuracy)
Garchomp @ Rocky Helmet
Ability: Rough Skin
EVs: 252 Atk / 4 SpD / 252 Spe

Jolly Nature
- Earthquake
- DragonClaw
- Iron Head
- Swords Dance

From experience I've tried all three and found dragon claw to be the better option if you're not running scarf. Outrage leaves you locked in and prone for setups on dragon resistant pokemon, and dual chop has a chance of missing, which in my opinion isn't worth it considering its power. Keep it simple with dragon claw and save yourself from misses and enemy setups.
Side Note: Reversal mega Heracross isn't a good idea! Reversal mainly only works for predicted 1hit KO moves, which mean you would need some sort of concept to hold you through it such as sturdy or Focus Sash, so it's not too much power or effectiveness with a regular moveset. I suggest Arm Thrust as a replacement as it goes better with its Skill linked mega.
Have fun teambuilding!
