Hey there..
This team probably isnt good but I just want to know how to improve it, etc.
Tyranitar@Chople Berry
Trait: Sandstream
EVs: 252 HP / 64 SpA / 192 SpD
Sassy Nature
~ Stealth Rock
~ Crunch
~ Fire Blast
~ Ice Beam
I Use this as my Summoner for Sandstorm and I think that this is a semi strong special wall that is effective. It also serves as a tank for quite a while and has checks like Fire blast and ice beam.
Garchomp@Life Orb
Trait: Rough Skin
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
~ Sword Dance
~ Outrage
~ Earthquake
~ Stone Edge
This is for sweeping once its set up as well. I am not too sure about what to put in place for the stone edge or if I should keep it but with outrage and the jolly nature and sword dance.
Terrakion@Choice Band
Trait: Justified
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
~ Close Combat
~ Stone Edge
~ X-Scissor
~ Sacred Sword
Close Combat with the sacred sword and choice band makes for a very strong STAB attack. I feel like its attack stat paired with its stellar speed stat creates for a great alternate sweeper to Garchomp.
Skarmory@Shed Shell
Trait: Sturdy
EVs: 252 HP / 232 Def / 24 Spe
Impish Nature
~ Roost
~ Spikes
~ Whirlwind
~ Taunt
I use skarmory when I am in a tight spot, and need a defensive wall that causes damage to a certain pokemon. Taunt is used for causing damage and roost keeps my skarmory healthy.
Starmie@Choice Specs
Trait: Natural Cure
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
~ Surf
~ Thunderbolt
~ Icebeam
~ Psyshock
Ok... so starmie is a really good check for counters to my team and can revenge kill a lot of my sandstorm pokemon weaknesses too. Especially with the 252 Spa.
Blissey@Leftovers
Trait: Natural Cure
EVs: 4 HP / 252 Def / 252 SpD
Bold Nature
~ Wish
~ Protect
~ Seismic Toss
~ Toxic
Blissey I use as my main special wall and this wish blissey is so strong. I can switch in blissey against a special attacker and throw toxic on them and protect. From here I can use Wish and switch into a different sweeper which heals my sweeper to full health even if they almost get 0HKO'd.
