STATS
NOTE: ?? means I am unsure, also I am not the best at modifying ev's, so if you know of any "perfect ev's" just let me know

Lead - Bronzong
Heatproof - Macho Brace - Sassy
252 hp/ 200 def/ 58 SpD
-Trick
-Gravity
-Hypnosis
-Stealth Rock
Bronzong has great defenses and can easily set up gravity and maybe even SR. With gravity it gets a 100% hypnosis which is great. There is a pretty simple way for this set: Trick, Gravity, then Hypnosis or Stealth Rock depending on the threat. I know some of you are wondering why the heck i am using Heatproof and the answer is quite simple, gravity makes ground moves always hit, so levitate would be pointless.

Sp wall/gravity support - Blissey
Serene Grace - Leftovers - Calm/Modest ??
196 hp/ 252 SpA/ 62 SpD
-Aromatherapy
-Fire Blast
-Gravity
-softboiled
Blissey is the best special wall, it can take the hits that bronzong can't and also can help set up gravity. With Serene Grace it can easily burn her opponent.

Def wall/spikes+tspikes/rapid spinner - Forretress
Sturdy - Shed Shell - Relaxed
252 hp/ 6 def/ 252 SpD
-Spikes
-Toxic Spikes
-Rapid Spin
-Explosion/Gravity ??
Forretress is also a great defensive wall AND it can also set up gravity and spikes/toxic spikes. Spikes and Toxic Spikes are so helpful with this team because they will effect all pokemon (except steel for toxic spikes)

Spe Sweeper - Gengar
Levitate - Life Orb - Modest
6 def/ 252 spe/ 252 SpA
-Hypnosis
-Focus Blast
-Thunder
-Shadow Ball
All of my tanks have one weakness in common, fighting. So I put gengar in here not only to disable and eliminate with hypnosis and focus blast, but to take those pesky close combats.

Spe Sweeper - Starmie
Natural Cure - Choice Specs - Modest
6 hp/ 252 spe/ 252 SpA
-Hydro Pump
-Blizzard
-Thunder
-Hidden Power fire
Starmie is my second special sweeper. With its speed and special attack, and ability to get rid of status problems, it can tear through teams with 100% accuracy moves

phys sweeper - Ryhperier
Solid Rock - Life orb - Jolly
252 att/ 252 spe/ 6 SpD
-Rock Polish
-Earthquake
-Stone Edge
-Megahorn
It was obvious that I needed a physical sweeper to fill my last spot. I love RP rypherior just because once it gets its speed boost, it is amazing.
