Ran out of "t" words for the title... I finally made a team that seems to win more than lose so I thought it would be worth improving here. It uses the mighty tyrannic Tyranitar.
Swampert@leftovers
Relaxed
240hp, 216def, 52 spA
Earthquake
Ice Beam
Roar
Stealth Rock
The basic Mixpert. I chose Swampert to be on my team because of his typing. He resists fire and is neutral to ground the 2 main weaknesses of my team. He also is packing super effective moves for both. Swampert makes an excellent lead and is immune to sandstorm making him fit well in this slot.
Plus Swampert is just awesome :p
Latias@leftovers
Calm
252hp, 184spe, 72spD
Calm Mind
Recover
Dragon Pulse
Surf
Latias has taken over Celebi's job of killing grounds. Unlike Celebi he has a fire resist. With surf he takes care of fire and ground poke's if the need arises. Latias can also threaten with a sweep in a pinch which Celebi couldn't. Recover keeps him alive in the sandstorm.
Magnezone@Choice Scarf
Timid
4hp, 252spe, 252spA
Thunderbolt
HP Fire
Signal Beam
Explosion
Magnezone is here to kill Scizor. Scizor is the biggest counter to Tyranitar there is so why not a poke who can kill him easily. Magnezone is no slouch even without Scizor though. He functions as a good revenge killer when Dugtrio can't do the job. His typing makes switching in pretty easy as well.
Bronzong@Light Clay
Levitate
Relaxed
252hp, 86att, 80def, 92spD
Light Screen
Reflect
Earthquake/Gyro Ball
Explosion
Dual screening Bronzong. With dual screens up Tyranitars above par defenses become even higher allowing it to get it's groove on and set up for the sweep. A scizor bullet punch does 162 max against t-tar behind reflect. Would earthquake or gyro ball be better in that slot? I'm thinking earthquake but I may be wrong here. Should Gliscor go here? It would make my team very water weak but it would use sandstorm better.
Dugtrio@Choice Scarf
Adamant
44hp, 252att, 212spe
Earthquake
Stone Edge
Night Slash
Aerial Ace
My two main weaknesses are fire and ground. Add 130 spA to the mix and you have the offensive beast that is Heatran. Flygon was in this spot but can't take even resisted fireblasts over and over. Same with Swampert. Thus the need for Duggy here. He can also kill Infernape who's Fire and Fighting attack are almost as bad. He has proved his usefulness many times.
Tyranitar@leftovers
Jolly
6hp, 252att, 252spe
Dragon Dance
Crunch
Stone Edge
Fire Punch
T-tar is the base of this team it all revolves around him. I don't need a reason to have him here he is the reason everyone else is here. He is a beast. Not much useful things to say about him though...
To recap there is Swampert, Celebi, Magenezone, Bronzong, Dugtrio, and Tyranitar. All barring T-tar is switchable if the need is there. Sorry I'm new to this RMT stuff so if it is subpar excuse me.
