Now this team was made for 3 vs 3 PBR Random Wi-Fi Battles so its bit more random than your standard OU play. Some threats very prevalent in that enviorment rarely make appearances on here so I'll tell you if you advice is usable.
For example: You might wanna add X-Scissor to Gliscor to handle Celebi
Havent ever faced a Celebi so yeaz.
Note: No lead needed, its really just prediction.
Arcanine @ Leftovers
Ability: Intimidate
EVs: 190 HP/ 200 Def/ 48 SAtk/ 72 Spe
Bold Nature
-Will-o-Wisp
-Flamethrower
-Hidden Power [Ice]
-Roar
Arcanine, believe it or not, is a great Physical Wall. Intimidate/Wow leaves Stone Edges, and Earthquakes, Waterfalls at low damage. He usually attracts a switch with the right prediction can allow me to burn another pokemon, or roar to see the whole team. Fire/Ice provide decent coverage being able to beat out Dragons, Steel, Grass, Flyers, Bulky grounds, and Ice bulky waters tend to laugh at Arcanine but he doesn't like staying in on them anyway.
Kingdra @ Leftovers
Ability: Swift Swim
EVs: 180 HP/ 252 Atk/ 76 Spe
Adamant Nature
-Waterfall
-Outrage
-Return
-Dragon Dance
Physical Kingdra, Water, Dragon provide excellent coverage as well as dual STAB, Return is a essentially a filler was considering Double Dance but that screws over Arcanine and Sceptile. Kingdra soaks up fire attacks aimed at Sceptile or Magnezone, and Water attacks aimed at Arcanine.
Sceptile @ Leftovers
Ability: Overgrow
EVs: 156 HP/ 100 Def/ 252 Spe
Jolly Nature
-Leaf Blade
-Leech Seed
-Substitute
-Hidden Power [Fire]
Sceptile, no longer the fastest Subseeder due to Shaymin-S. This set is a Mixed Leaf Blade/ HP Fire attacking version, to catch a weakened Calm Mind Suicune as well as hit Blissey for some damge, and HP Fire to get rid of Skarmoy, and other steels/grasses who think they will be waltzing over Sceptile. Works well in conjuction w/ Arcanine's Burn or Gengar's Sleep.
Gengar @ Black Sludge
Ability: Levitate
EVs: 64 Atk/ 192 SAtk/ 252 Spe
Hasty Nature
-Shadow Ball
-Hypnosis
-Focus Punch
-Substitute
Sub Punchin' Gengar, works wonders w/Perfect coverage and the ability to beat out many common threats to this team. Sub/ Punching or Hypnosis Punching is what he was made for while Shadow Ball provides a solid stab move. If Magnezone cant get up a Magnet Rise then Gengar can switch in to avoid earthquakes as well as fighting moves, or an earthqauke aimed at Arcanine.
Magnezone @ Leftovers
Ability: Magnet Pull
EVs: 172 HP/ 252 SAtk/ 84 Spe
Timid Nature
-Thunderbolt
-Hidden Power [Ice]
-Metal Sound
-Magnet Rise
Magenzone serves as a wall breaker believe it or not, and with an Rock Polish under it's belt is even more of a threat. Bolt Beam coverage so the only thing that gets pass is Laturn/Shedninja. Metal Sound is the key to this set with a STAB Thunderbolt coming off a 359 SAtk, Metal Sound basically ensures a KO on anything excluding Blissey, and boosted Special Walls. Magnet Rise allows me to avoid ground moves, and can Sponge Ice/Dragon attacks aimed at Gliscor and Kingdra respectively.
Gliscor @ Leftovers
Ability: Hyper Cutter
EVs: 252 HP/ 24 Atk/ 96 SDef/ 138 Spe
Impish Nature
-Rock Polish
-Earthquake
-Stealth Rock
-Baton Pass
Gliscor, now i had no use for an all out attacking or defensive Gliscor so I decided to try out Sub-Passing so that Sceptile and Gengar could set up easier, but it proved useless so i decided to try speed passing. Helps Magnezone set up alot faster than usual gives Kingdra an extra boost in speed, and help Arcanine roar out faster threats. Stealth rocks does a bit of extra damage to things switching in and out, to help break sashes and whittle my opponents down. Walls fighting moves aimed at Magnezone as well as avoid earthquake and thunderbolts.
So this is my team, looking for anything you see as a big threat that can tear through my team, or any improvements to be made. So that's all RMT.
