I've taught myself basic competitive battling for about a year now and this is another one of my attempts at a normal pokemon team, no theme or anything.
The team is doing decently, I used to be trapped at mid 1500s on PS, but with this team I can get around 1700. I always choke when I'm about to get there however, lol.
Anyway team building process; I needed a strong defensive lead that could set up stealth rocks, I chose Metagross for his high defense stat and steel typing.
For my second poke, I wanted another defensive poke that could cover threats metagross couldn't, mainly bulky grounds and heatran; I picked jellicent.
Now to start picking some offensive pokemon. I picked CB Tar for pursuit and raw power.
So I had the physical, and now I wanted the special. I went with CS Latios as he compliments and works with Tyranitar very well.
Now, for the last pure offensive pokemon, I needed something that would cover Scizor, Ferrothorn, and other bulky waters. I went with Zapdos, he ended up working really well with the team. Has moderate surprise factor too.
I really love having rapid spin support, so I debated whether to choose Donphan or Starmie. I picked Donphan for more bulk and less redundant coverage than Starmie (teamwise).
After a while, I felt like Metagross wasn't really pulling his weight. Stealth rock was redundant, and ground types destroyed him. I still needed the steel typing, high defense, and entry hazard support, so I replaced him with Skarmory.
I later felt as though Jellicent was a little too passive and fragile. I realized I ended up using him as death fodder for most of my matches so I decided to replace him with someone who can still spread status, take hits, and counter rain team. The last change I made was replacing Jellicent with Rotom-W.
So there's the first copy of the team. Onto the sets!
Skarmory@Leftovers
Sturdy
Impish 224Hp/248Def/32SpD/4Spe
Brave Bird
Spikes
Whirlwind
Roost
Skarmory's pretty cool. He sets up spikes, can switch in and phaze to relive pressure from opponent. Brave Bird does surprising amounts of damage. Not much else to say, he's a great wall and supporter.
Rotom-W@Leftovers
Levitate
Modest 232Hp/54SpA/224Spe
Will-O-Wisp
Hydro Pump
Volt Switch
Hidden Power Ice
Rotom-W's good at annoying. He can switch in heatran and other bulky attackers and either cripple or KO them. Volt Switch is good for keeping momentum. His coverage may be a bit redundant with the rest of the team, but electric and ice moves tend to be helpful in bulk.
Tyranitar@Choice Band
Sandstream
Adamant 154Hp/240Atk/104Spe
Crunch
Pursuit
Stone Edge
Superpower
Tyranitar's good at wall-breaking. Pursuit's awesome for trapping psychics and ghosts. Not much to say. Usually nets at least 1 kill per game, and next to nothing can switch into it. Speed evs are to outspeed skarmory and other CB/Stealth rock Tyranitars.
Latios@Choice Scarf
Levitate
Timid 4Hp/252SpA/252Spe
Draco Meteor
Thunderbolt
Psyshock
Surf
Latios is great for dealing with pokemon Tyranitar has trouble with. Psyshock KOs the multiple fighting types that would give this team trouble otherwise. Draco Meteor's the go to move, being stronger than super effective surf or thunderbolt. With CS, Latios can OHKO and check every dragon dance user in OU even with +1.
Zapdos@Expert Belt
Pressure
Modest 4Hp/252SpA/252Spe
Thunderbolt
Heat Wave
Roost
Hidden power Ice
Zapdos is a big help to the team providing a lot of coverage and checking threats such as ferrothorn, breloom, politoed, dragon/flyings, ground/flyings, Abomasnow, and tons of bulky waters. Rotom-W shares some attacking types, but I find myself often losing one or the other, and I really can't afford to lose access to electric/ice moves. I chose Modest nature because timid rarely outspeeds anything of importance, while the extra power is significantly appreciated. Zapdos also can make some amazing comebacks often KOing 3 pokemon in a row. I chose him over thundurus-T for heat wave and roost.
Donphan@Leftovers
Sturdy
Impish 252Hp/252Def/4Spe
Earthquake
Ice Shard
Stealth Rock
Rapid Spin
Donphans good at walling heavy hitters, setting up rocks, and proving rapid spin support. Also checks lots of fire and steel types. Sturdy's cool and Ice shard can be a great finishing move.
So there it is, I don't remember everything about making it, but I do remember that I put in significant time thinking about it. Any and all improvements will be welcome. The team is good, but I want to make it great. If the team is solid, please let me know so I can focus on honing my battle skills rather than spending hours in teambuilder.
