Ok I've been playing around with teams for a while, but I finally arrived at one that I don't think sucks.
Skarmory @ Leftovers
Ability: Keen Eye
252 HP/4 DEF/ 252 SDEF: Impish Nature (-SPA, +DEF)
-Stealth Rock
-Spikes
-Whirlwind
-Roost
This is pretty much a standard lead. Just set up all the hazards that it can. Whirlwind for passive damage and Roost as needed.
Scizor @ Life Orb
Ability: Technician
252 ATK/4 HP/252 SPE: Adamant Nature (-SPA, +ATK)
-Swords Dance
-Bullet Punch
-Brick Break
-Roost
This is my sweeper and, quite frankly, my favorite sweeper. I just switch him in on a resisted move or a resisted Pokemon and Swords Dance away. Bullet Punch is the standard for Scizors and Brick Break hits all those Pokemon who resist Bullet Punch. Roost is to keep his reign of terror going
Gliscor @ Leftovers
Ability: Sand Veil
252 HP/40 DEF/216 SPEED: Jolly Nature (-SPA, + SPE)
-Taunt
-Earthquake
-U-Turn
-Roost
Gliscor is good at taking the hits that would dominate my Skarmory, Breloom, Scizor, or Jirachi. He can also break some of the annoying walls or phazers that could stop my team. The Jolly is so he can Taunt and outspeed threats to my team, or just stop them in general.
Starmie @ Leftovers
Ability: Natural Cure
136 HP / 156 Def / 216 Spe: Timid Nature (-ATK, +SPE)
-Rapid Spin
-Thunderbolt
-Surf
-Recover
This is the Rapid Spinner of my team. He comes in and Rapid Spins all the entry hazards away so my team can continue working. He can also counter the Waters used against Gliscor, or he can counter the fires that dominate Scizor, Breloom, Jirachi, and Skarmory. Gyarados is also a troublesome Pokemon for my team, and Starmie handles it quite well.
Breloom @ Toxic Orb
Ability: Poison Heal
252 ATK/4 HP/252 SPE: Jolly Nature (-SPA, +SPE)
-Focus Punch
-Spore
-Substitute
-Seed Bomb
To begin with, it may seem silly to run Jolly on a Breloom, but it's necessary to get Spore and Sub up easily. Once he Spores the opponent he's pretty much done. This is the standard Breloom SubPuncher set. It eliminates those water types that annoy Gliscor, and the darks that can remove my Rapid Spin Starmie support.
Jirachi @ Choice Scarf
Ability: Serene Grace
4 HP/252 ATK/252 SPE: Docile Nature (No effect)
-Ice Punch
-Fire Punch
-Iron Head
-Trick
The only reason for Docile is that it was the only Legitimate Jirachi I could get with a nature remotely favorable for this set. He provides the key dragon type resistance and coverage. The scarf allows him to outspeed those that could actually end him quickly. Fire Punch gives me the firepower (haha pun) I need and Iron head is the STAB with the flinch I can abuse because of Choice Scarf. Trick is just to stop annoying walls that are just ticking me off.
I hope this team is good enough lol. The only problem is the lack of a spin blocker to protect the hard work of Skarmory, but Skarmory works well as a wall too so I think it works out. Also, me and my friends have this thing where we can't have the same Pokemon as one another. They took all the ghosts (except Froslass, but she is bad anyway) and Rotom-H doesn't work in Wi-Fi.
