Hey everybody. I'm trying to get into the game for the first time, and after lurking for a while, making a rain team sounds pretty attractive to me. The general idea is that I use Toxic Spikes, Scald, and the like to inflict my opponent with status and then proceed to wear them down with bulky, self-recovering pokes who benefit from the rain.
That being said, I have NO experience with pokeymanz, so you guys are going to need to be very generous with your analysis and fixes. The team is my first one, and I've only just begun using it.
Anyways, here's the team:

Anyways, here's the team:

Politoed
Drizzle w/ Leftovers
Bold: 252 HP/ 252 Def / 4 SpD
Bold: 252 HP/ 252 Def / 4 SpD
-Scald
-Toxic
-Perish Song
-Protect
-Toxic
-Perish Song
-Protect
Duh. What would any rain team be without this guy? Since I decided I wanted this to be a more slow paced team with an emphasis on outlasting opponents, I went with the bulky set. He lacks any form of self-recovery, but I digress. EV's are pretty straightforward, maximizing HP and defense.
Scald serves as the set's attacking move should I attempt to deal some damage with this guy, and the burn chance is nice. Toxic is the go-to move for the set, providing me with a means of outlasting the foe. Perish Song is for stallbreaking, should the need arise, and Protect is for scouting.

Jellicent
Water Absorb w/ Leftovers
Calm: 252 HP/ 36 Def / 220 SpD
Calm: 252 HP/ 36 Def / 220 SpD
-Scald
-Recover
-Toxic
-Ice Beam
-Recover
-Toxic
-Ice Beam
Toxicroak was originally in this spot, but I switched it out for Jellicent because I needed a spinblocker and a special wall. Jellicent performs both of those roles well, as well as forming the Ferrothorn-Jellicent defensive core. The given EV's maximize special bulk while allowing me to avoid a 2HKO from Starmie's Psyshock.
Scald is my STAB attacking move, Recover is for self-recovery, and Toxic is my win condition. Shadow Ball provides me with coverage against opposing ghost-types, Celebi, Reuniclus, and the like, but I may switch it out for Ice Beam.

Tentacruel
Rain Dish w/ Black Sludge
Bold: 252 HP / 240 Def / 16 SpD
Bold: 252 HP / 240 Def / 16 SpD
-Toxic Spikes
-Rapid Spin
-Scald
-Protect
-Rapid Spin
-Scald
-Protect
Ideally, this guy should be providing me with my win condition most of the time. Toxic Spikes poisons every non-steel type pokemon upon switching in, and from that point on I just need to outlast them. Rain Dish is nice, although not quite as nice as Dry Skin, so he'll be getting 1/8 of his max HP back per turn when combined with Black Sludge. Like the others, these EV's maximize bulkiness, with an emphasis on physical defense.
Toxic Spikes is the key move, with every opposing pokemon barring steel-types being badly poisoned after two layers. Rapid Spin helps out my sweepers, but it's not crucial since I don't have a glaring weakness to Stealth Rock. Scald provides me with an attacking move, and Protect is for getting a free turn of poison damage.

Dragonite
Multiscale w/ Leftovers
Calm: 248 HP / 108 SpA / 148 SpD
Calm: 248 HP / 108 SpA / 148 SpD
- Thunder
-Hurricane
-Roost
-Dragon Tail
-Hurricane
-Roost
-Dragon Tail
Rotom-W was originally in this spot, but it was changed to Dragonite as per BTzz's suggestion. Dragonite fills several roles for the team, providing an answer to threats such as Volcarona, Venusaur and Breloom. He also works well as a phazer with Dragon Tail, and has the bulk to stall out the opponent using Roost and Multiscale.
Thunder hits a lot of threats for massive damage, most notably Skarmory and SubCM Jirachi. Hurricane takes care of the Grass types who would have a field day with this team otherwise. Roost serves as his self-recovery, and combos well with Multiscale for stalling. Dragon Tail allows Dragonite to function as a phazer, preventing threats such as Jirachi from setting up and forcing opponents into Tentacruel's Toxic Spikes.

Ferrothorn
Iron Barbs w/ Leftovers
Relaxed: 252 HP / 88 Atk / 168 SpD
Relaxed: 252 HP / 88 Atk / 168 SpD
-Spikes
-Stealth Rock
-Power Whip
-Bulldoze
-Stealth Rock
-Power Whip
-Bulldoze
We all know this guy, so I'm not going to put too much into the explanation. Pretty standard on most rain teams, and perhaps the majority of teams in the OU tier. His main job is to check threats to the team such as Tyranitar, Latios, and opposing water types looking to profit from the rain. EV's maximize health, and enable him to take both physical and special hits well, as well as deal some damage.
Spikes and Stealth Rock give him somethig to do while he's walling, and are nice when paired with Tentacruel's Toxic Spikes. Leech Seed was originally in Stealth Rock's spot, but was replaced upon BKC's suggestion to allow me to better handle threats such as Tornadus. Power Whip is his main attacking move. Gyro Ball was originally in the last slot, but I changed it to Bulldoze as per BTzz's suggestion in order to cover threats such as SubCM Jirachi. I also changed the Def EV's to Atk in order to break Jirachi's subs.

Scizor
Technician w/ Choice Band
Adamant: 248 HP / 252 Atk / 8 SpD
Adamant: 248 HP / 252 Atk / 8 SpD
-U-Turn
-Bullet Punch
-Superpower
-Pursuit
-Bullet Punch
-Superpower
-Pursuit
The idea behind Scizor is to kill everything that normally poses a threat to rain teams, such as Virizion, Breloom, and once again, Tyranitar. It is also an excellent revenge killer, knocking out most opposing sweepers with a single STAB Bullet Punch provided they don't resist it.
U-Turn allows me to scout out my opponent's pokes and send in an appropriate counter, and Bullet Punch is my main STAB. Superpower allows him to take on his usual counters, such as Heatran and Magnezone, as well as some other steel-types who give this team trouble. Pursuit ensures the KO against weakened pokes that I predict will switch out.
So, there you have it. Keep in mind once more that this is my first competitive team, and I will be humble about the vast changes that are probably necessary.
