Here is my team for VGC 2016
Ditto @ Red Card
Ability: Imposter
Level: 50
Shiny: Yes
EVs: 252 HP / 252 Spe
Timid Nature
- Transform
Ditto is used when there is a good pokemon is on the field or a pokemon with some stat boosts is on the opponents team. Red card can get rid of pokemon with stat poosts. Its used for general trolling and is pretty unpredictable. Further more it isnt seen much in VGC.
Weavile @ Life Orb
Ability: Pressure
Level: 50
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Fake Out
- Knock Off
- Ice Shard
- Ice Punch
Fast and hard hitting. Knock Off and Fake Out provide good utility while Ice Punch provides good STAB. Ice Shard used when I am not fast enough to hit and I know I am going to get KO'ed. Life Orb provides more damage.
Whimsicott @ Focus Sash
Ability: Prankster
Level: 50
Shiny: Yes
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
- Worry Seed
- Dazzling Gleam
- Taunt
- Leech Seed
Whimsicott is great to get rid fo Mega Rayquaza as Worry Seed takes away Delta Stream and an Ice Beam from Kyogre or Ice Punch from Weavile takes it out. Taunt and Leech Seed are used as support. Focus Sash lets it survive as it defenses are weak.
Regirock @ Sitrus Berry
Ability: Clear Body
Level: 50
EVs: 4 Atk / 252 Def / 252 SpD
Impish Nature
- Thunder Wave
- Drain Punch
- Stealth Rock
- Rock Tomb
Since this year many Uber pokemon have been allowed in the comp, I have noticed that many of them are physical attackers so I have included Regirock as it has a high defensive stat and decent attack so it may do some damage on the field. Thunder Wave is used to distrupt fast pokemon, Stealth Rock to break Sashes, Rock Tomb to lower speed and Drain Punch to recover HP.
Mewtwo-Mega-Y @ Mewtwonite Y
Ability: Insomnia
Level: 50
EVs: 252 Def / 252 SpA / 4 Spe
Modest Nature
- Reflect
- Will-O-Wisp
- Aura Sphere
- Psychic
As said before, many of the pokemon to be used next year are physical attackers. Mewtwo has access to Reflect and Will-O-Wisp to help put these out. Psychic and Aura Sphere provide decent damage.
Kyogre-Primal @ Blue Orb
Ability: Primordial Sea
Level: 50
EVs: 252 Def / 252 SpA / 4 Spe
Serious Nature
- Origin Pulse
- Thunder
- Ice Beam
- Protect
Primal Kyogre is a Sp. Def Tank and can handle many other Pokemon. The 4 EVs in speed allow it to outspeed all other Primal Kyogre's and hit them hard with Thunder.
