INTRODUCTION
After making a successful anti-weather team I tried to make a classic team that is not related to anything except type coverage and balance.This team is all based on good predictions, rarely does it become a sweep.
Team at a glance:
Now to the analysis:
Ferrothorn (M) Leftovers
Ability:Iron Barbs
Ev's: 252 hp/208 Sp.Def/ 48 def
Relaxed Nature(+ Def, -Speed)
Spikes
Leech seed
Gyro Ball
Power Whip






Now to the analysis:

Ferrothorn (M) Leftovers
Ability:Iron Barbs
Ev's: 252 hp/208 Sp.Def/ 48 def
Relaxed Nature(+ Def, -Speed)
Spikes
Leech seed
Gyro Ball
Power Whip
This ferrothorn is very useful, as all the others. He is a classical hazard setter. And he is my very successful mixed wall. With Gyro Ball and power Whip he's got a nice coverage on comon taunters. I personally like leech seed more than stealth rocks because he can recover his health back because he does not have any recovery moves. His Gyro ball can be sometimes very powerful that's why this ferrothorn is a problem for every team. He is also useful because he covers the flying type which is the common weakness of conkeldurr and volcarona. In a nutshell this pokemon is very useful to this team on the defensive and sometimes even on the offensive side.
Starmie () Lifeorb/Expert belt
Ability: Natural cure
Ev's: 252 speed/252 Sp.att/ 6 hp
Timid Nature(- Attack, +Speed)
Rapid Spin
Hydro Pump
Recover/Ice beam
Thunderbolt
The main role of Starime is to move the hazards away especially the stealth rocks and toxic spikes. My team is pretty weak to stealth rocks and toxic spikes, that's why I decided to use Starmie. Starime's speed and decent special attack made me put it in. It is perfect against thundurus and gliscor who are a big threat to my team. What is different between starime and other rapid spinners is that it is much faster than the others and can hit hard if you predict a rapid spin blocker. Starmie is also there to balance my team in offensive sides (attack/special att.) It also covers the typing and is resistant to fighting moves which is also a problem, but starmie is just the second option because i have gliscor to take care for the fighting pokemon.
Conkeldurr (M) Leftovers
Ability: Guts
Ev's: 252 attack/120 hp/ 136 Sp.def
Adamant Nature(+Attack, - Sp.att)
Bulk up
Mach punch
Drain punch
Payback
Conkeldurr is the MVP of this team. He is very special to my team because he is a fighting type with enormous attack and bulk. All the other fighting pokemon are pretty weak compared to this beast. Terrakion was an option as well but beacuse he has many weaknesses i chose conkeldurr. Conkeldurr's main role is to take hits when gliscor and ferrothorn can't and kick in when the special attackers of the opponent are weakend. He can even be a revnge killer with mach punch. He can even stop a +2 scizor from sweeping my team. By +2 i mean when i switch on the turn the scizor uses swords dance. He destroys all steel types and protects starmie from the dark pokemon. He might not seem the key pokemon, but he has that special "something" that helps my team a lot. I tried many times playing with this team without conkeldurr and it never worked. I honestly don't know the exact answer why is this conkeldurr so important :D . However, this beast has its weaknesses as well, and that is the specially defensive side. It is completely walled by almost all psychic pokemon.
Volcarona (F) Leftovers
Ability: Flame Body
Ev's: 252 speed/6 hp/ 252 Sp.att
Timid Nature(+speed, - attack)
Quiver Dance
Fire Blast
Bug Buzz
Hidden Power [Ground]
This pokemon is just wonderful.My most important offensive pokemon. After setting up 2 quiver dances it is surely ready to sweep. Sometimes even blisseys can't stop this thing. It surely is hard to set up, but because i have starime to constantly remove hazards i wait for the perfect moment to switch into Volcarona and then eventually sweep. This pokemon also is a secondary option against fighting threats. It has some sp.def bulk and can hits decently. This thing can ohko vaporeon after 2 layers of spikes and stealth rocks with a +1 bug buzz. You might think this pokemon is way better than conkeldurr, it can sweep! Well i say no, if starmie dies and the opponent sets up late SR's my volcarona is screwed up. I don't use life orb on this pokemon because if i switch in and the SR's are set up i don't want to keep losing health with lifeorb, because i might need volcarona later even with little health.
Gliscor Toxic Orb
Ability: Poison heal
Ev's: 252 hp/ 176 def/ 80 Speed
Impish Nature (+defense, - sp.att)
Toxic
Protect
Earthquake
Ice fang
The main reason why I put in gliscor is because I needed to balance my team.I didn't have both a ground or flying poke that's why the choice went on either gliscor or landorus. But after debating which one should i take i decided to take gliscor because of his ability and defense. I use gliscor to set up toxic and stall the opponent. I don't really like stalling a lot but gliscor just fits in my team. With ice fang and earthquake it has a nice coverage. Gliscor is my second defensive wall in my team. The main reason why i have 2 walls is because ferrothorn can't recover his hp as eficiently as gliscor.
Blissey Leftovers
Ability: Natural cure
Ev's: 252 hp/ 252 def/ 6 Sp.Def
Bold Nature (+defense, - attack)
Thunder Wave
Seismic toss
Stealth rocks
Softboiled.
Blissey is my pure special wall. It can take and special hit you serve to it, just like an ordinary blissey. I have thunder wave on it to cripple my opponent. It might be a little weird why i have stealth rocks on blissey, but it is actually very useful. I use stealth rocks when a latios, for example, wants to switch out after using DM. Blissey was the only available special wall because the others won't fit in the team beacuse their types don't fit in the team. Blissey works very nice when together with gliscor.
Overall, this team is pretty nice. It is very successful on PO. In order to play with this team successfully you have to have good prediction skills, and you have to risk sometimes with volcarona in order to succeed. From my experience 80% of the risks i made with volcarona were successful and the other 20% failed because i made some stupid mistakes.
Please feel free to rate my team and give me as many advices as you wish. Please tell me if you find any spelling or grammar mistakes. I would appreciate that.
Counter: In my opinion i think Rotom-W is a counter, even though after setting up a quiver dance with volcarona it is not a problem. Expert belted Latios is a terrible problem, because i can never 100% know whether he has a choice item. So he can hurt blissey with psyshock. I don't think this team has any other counters.
