Ok so my team is mostly an offensive one. I'm running a few underrated sets that people don't really expect in competitive play. This is my first post so bear with me.
At a Glance:
I started this team with a Bulky Dragon Dance Gyarados set in mind.
Gyarados @Leftovers with Intimidate
Adamant 176 hp / 128 atk / 204 spe
Dragon Dance
Waterfall
Taunt
Stone Edge
This set allows it to take more hits and set up a little safer with the extra bulk it carries. Gyarados can set up on numerous offensive threats and typically force switches to get in some boosts and also allows him to set up on pokemon that would normally give him trouble such as Skarmory and Ferrothorn and most likely force a switch. Gyarados can also come in numerous times and sponge a hit or two if need be with the added bulk. With this setup Gyarados has a nice blend of power and survivability. however if i was going to be switching him out and in often for potential sweeps i was going to need rapid spin support and pokemon that could deal with all of the potential counters to a bulky set such as bulky water types bulky grass types and bulky pokemon in general like Porygon2 and a pokemon who could get Stealth rocks up rather quickly and efficiently at the start of a match wouldn't be so bad either. All of these pokemon would play a vital role in helping my Gyarados sweep.
As far as Spinners i wanted something fast and something that could hit like a truck all in one. For this i found Starmie met my needs perfectly.
Starmie @Life Orb with Natural Cure
Timid 252 spa / 4 spd / 252 spe
Hydro Pump
Thunderbolt
Ice Beam
Rapid Spin
This is your basic Starmie setup that i don't think needs much explaining. you have Hydro Pump for a powerful STAB move along with BoltBeam coverage. Life orb to give it a little extra kick when attacking and can often score some KOs, especially with Stealth Rock damage and can also assist as far as dealing with bulky water types and dragon types as well.
As far as defensive prowess, dealing with bulky water types and having an excellent wall i decided Ferrothorn was the way to go.
Ferrothorn @Leftovers with Iron Barbs
Relaxed 0 Spe IVs 252 hp / 88 def / 168 spd
Spikes
Leech Seed
Protect
Gyro Ball
This is a pretty basic Ferrothorn setup here. Not much to explain. The evs and nature give him some pretty balanced defenses so that he can some a ton of hits a do whatever he wants in return. just has to be wary of them fire types is all...
Then as for dealing with bulky grass types and hitting most anything else like a truck while being able to take a few hits of his own i turned to Heatran.
Heatran @Air Balloon with Flash Fire
Timid 252 spa / 4 spd / 252 spe
Fire Blast
Earth Power
Hidden Power (Ice)
Toxic
Heatran can take on opposing Heatran and ohko Gliscor and Landorus as well as Dragon Types. Toxic gives Heatran a way of dealing with pokemon that would normally wall Heatran till kingdom come such as the ever present pink blobs.
As far as taking down generally bulky pokemon that gyarados would normally struggle to get past i decided to go with the bulky fighting type Conkeldurr.
Conkeldurr @Flame Orb with Guts
Adamant 224 hp / 252 atk / 32 spd
Drain Punch
Mach Punch
Payback
Facade
Bulk Up and Choice Band Conkeldurrs have to hope they can luckily switch into a status inducing move or the opponent accidentally status them while still being susceptible to sleep inducing moves. However this set eliminates all that hassle from the get-go. Drain Punch is Conkeldurr's obligatory STAB move of choice as it increases his longevity and deals a lot of damage with a Guts boost. Mach Punch can reliably revenge kill while Payback deals with opposing ghost and psychic types. Facade is the most powerful move on this set and can easily surprise defensive pokemon such as Reuniclus and Gliscor that would otherwise wall this set completely.
Last but not least i decided i would turn to the best blank slate pokemon has to offer for my fast, effective lead pokemon, Mew.
Mew @Lum Berry with Synchronize
Jolly 252 hp / 4 def / 252 spe
Stealth Rock
Taunt
U-Turn
Fake Out
This set aims to maximize overall bulk and speed to get Stealth Rock out as quick as possible. Taunt can frustrate opposing leads trying to set up Stealth Rock and Fake Out can break opponents sashes and U-Turn to keep up the momentum of the battle. Mew can also absorb a status hit if need be and return the favor with synchronize while healing off its own status problem with Lum Berry.
This is my OU team and any suggestions would be GREATLY appreciated! Thanks!
