Ok so this is my current team on Wi-Fi its been working great mainly because my prediction has been getting better and better so rate the team. This team is for the Standard Metagame.
Abomasnow @ Leftovers
Snow Warning
Sassy
252 HP / 160 SpD / 76 Spe / 20 SpA
~ Leech Seed
~ Wood Hammer
~ Blizzard
~ Protect
Oh why do we used this Yeti its stats are less than exiciting well he is are only Instant Hailer so get used to it. Abomasnow helps against many leads such as all those Sandstorm teams with Tyranitar and Hippowdon who will get hammered by Wood Hammer or Blizzard. Leech Seed is awesome sapping other Pokemon's Health. And Protect is cool for scouting.
Gliscor @ Leftovers
Sand Veil
Impish
252 HP / 252 Def / 6 Atk
~ Knock Off
~ Earthquake
~ Aerial Ace
~ Roost
Well if it wasn't for this guy countless Heracross and Swords Dancing Lucarios would have raped my team. Knock Off is even cooler in Hail screwing over all those Leftovers off of Pokemon. Earthquake and Aerial Ace are just for Stab. Roost is just plain out awesome.
Hariyama @ Leftovers
Thick Fat
Impish
252 Def / 204 HP / 54 Atk
~ Cross Chop
~ Rest
~ Stone Edge
~ Sleep Talk
No I am not using Guts I'm trying to wall with Hariyama and absorb status and with Thick Fat its easy to come in on Ice and Fire attacks. Your basic Sleep Talker.
Tentacruel @ Leftovers
Liquid Ooze
Calm
204 HP / 172 SpD / 96 SpA / 36 Spe
~ Rapid Spin
~ Toxic Spikes
~ Sludge Bomb
~ Surf
Special Wall can come in on a lot of Water Pokemon, Spins away Spikes and SR, Sets up Spikes.
Heatran @ Choice Specs
Flash Fire
Modest
252 SpA / 204 Spe / 52 HP
~ Earth Power
~ Overheat
~ Dragon Pulse
~ Explosion
Why I'm I not using Scarf? Well because most people will assume its a ScarfTran so thats why. Heatran with Choice Specs is a monster it 2HKOs Blissey with a Flash Fire boost and Hail or Toxic Spikes in effect heck Specs Overheat hurts just about anything that doesn't have high SpD + resistance. Dragon Pulse will knock out all those Dragons. Earth Power is great against Rock and Steels. Explosion hurts no matter what.
Mamoswine @ Leftovers
Snow Cloak
252 Atk / 124 HP / 68 SpD / 64 Def
~ Curse
~ Ice Shard
~ Earthquake
~ Rest
Bronzong walks all over this set and thats why I always hide Mamoswine for last or when Zong is out than proceed for the late game sweep. Curse is very helpful with Ice Shard and Earthquake just hurts. Rest is to heal. This functions like Snorlax and Suicune.
