So I made a new team. Here it is:
[Bronzong]
[Starmie]
Now, in detail:
Bronzong@Leftovers
252 HP, 80 Def, 86 SpA, 92 SpD
Calm
Levitate
-Psychic
-Shadow Ball
-Stealth Rock
-Hypnosis
Bronzong is one of my favorite leads, due to its good typing and general bulkiness. Leftovers increase its tanking ablities, obviously. I deviated from the standard Bronzong slightly, giving it the special moves Shadow Ball and Psychic instead of Earthquake and Gyro Ball, merely because I have no moves which are good against Psychic or Ghost pokemon, besides Bronzong's Shadow Ball, and no Psychic moves either, plus Psychic has STAB. Hypnosis for sleep support, and SR for... well... must I really explain? -_- I chose Levitate over Heatproof for obvious reasons, Levitate grants a complete immunity to one type, where as Heatproof merely makes the fire type moves do regular damage. The Calm nature is because, since I no longer have Gyro Ball, he decrease in speed will merely hinder. Therefore I picked a nature which would lower a stat I didn't care about, attack, while still raising special defense. The EVs allow it to tank while still doing a bit of damage.
Scizor@Life Orb
32 HP, 252 Atk, 224 Spd
Adamant
Technician
-Swords Dance
-Roost
-Bullet Punch
-Brick Break
Ah, Scizor. The most used pokemon in the metagame (I think...?). Still, it didn't become the most used for nothing. Although SD Scizor seem to be a dying breed (or not, but I haven't seen any lately), I like them. Swords Dance for obvious reasons, I mean it IS an SD Scizor. Swords Dance all I can and sweep. Roost lets me recover some HP as I sweep, in case of near deaths, and the fact that I get people using earthquake quite a lot, which usually does ~40%, and Roost restores 50%. Bullet Punch for STAB, priority, and the fact that with Technician, it does quite a lot of damage. Brick Break over Superpower, so I don't have to deal with the attack drop while I'm sweeping. Technician nature in order ot boost Bullet Punch's power to an extremely high amount. Adamant nature for the attack, as Scizor's low base speed, an the fact that Bullet Punch is the main move I'll be using, means a +Speed nature would be wasted. The EVs let me to occasionally outspeed things I wish to Brick Break, and the attack, to, of course, make my moves do more damage. Life Orb for the added damage.
Blissey@Leftovers
252 Def, 216 SpD, 40 SpA
Calm
Natural Cure
-Wish
-Protect
-Seismic Toss
-Toxic
The standard Blissey, really. Defensive EVs, since Blissey is made for stalling. It's the team's special wall. A Calm nature to raise SpD, which is Blissey's strong point, while minimizing attack, which is useless anyways. The ability Natural Cure means that if my Blissey is poisoned, or otherwise incapacitated, I can switch out and get rid of the negative status. Seismic Toss can do a bit of damage if I have nothing else in particular to do. Toxic so Blissey can stall while the opponent slowly dies. And what would a Blissey be without leftovers? 6% HP every turn helps me stall.
Starmie@Leftovers
136 HP, 156 Def, 216 Spe
Timid
Natural Cure
-Surf
-Rapid Spin
-Thunderbolt
-Recover
Starmie is, imo, the best rapid spinner there is. He's relatively bulky, Natural Cure prevents him from being crippled by Paralisys, poison and the like, His Timid nature and speed EVs let him outspeed many common threats, and his HP and Def EVs allow him to tank better. Rapid Spin to get rid of spikes, t-spikes and SR, Surf for STAB, and T-bolt helps with Gyarados and other water types.
Mamoswine@Life Orb
252 Atk, 252 Spe, 4 Def
Jolly
Snow Veil
-Stone Edge
-Earthquake
-Superpower
-Ice Shard
Mamoswine is one of my favorite pokemon. He's somewhat bulky, has good typing, and has amazing attack. The EVs let me outspeed quite a few threats, while still being able to do incredible damage. A Jolly nature, since that lets me outspeed the standard SD lucario. Since Mamoswine already has such high attack, I can get away with using a Life Orb instead of a Choice Band, so can still Ice Shard flying types without being locked into earthquake. Stone Edge helps me against Gyarados and such pokemon. Earthquake has STAB and is just a good move, overall. Superpower helps against, well, things that are weak against flying. Ice Shard for priority and STAB. Snow Veil lets me take advantage of opposing Hail teams.
Salamence@Choice Specs
4 HP, 252 Spe, 252 SpA
Timid
Intimidate
-Draco Meteor
-Dragon Pulse
-Hydro Pump
-Flamethrower
Although I prefer CB Salamence to Specs Mence, I really needed a special attacker, and specs mence does a great job. Draco Meteor with STAB and specs kills just about any dragon type, and kills about half of the things that aren't. Dragon Pulse has more reliable accuracy, and if I have to keep Mence in for a long time, then it's a better alternative than Draco Meteor, as there's more PP and no SpA drops. Hydro Pump for fire, ground, and rock types. Flamethrower for the types which it's good against. Especially Scizor. I chose a Timid nature, since that lets it outspeed a lot of common mence threats, along with the speed EVs.
_____________________________________________________________
Overall, this team has been performing pretty well, but I feel as if it's missing some things. I'd sort of like another set-up sweeper, as those can sometimes turn a game where you made some mistakes to your favor. I was thinking perhaps a Curselax, in place of Blissey as that could still semi-wall. Anyways, help me out please. Changes are in Bold.
