This is a team starring Mega Lopunny. This is a team I have got a few wins with and look like any suggestions tot help. People also don't expect Magnezone in VGC
Lopunny @ Lopunnite
Ability: Limber-Scrappy
EVS: 252 Atk / 252 Spe / 4 HP
Nature: Jolly
Fake Out
Drain Punch/High Jump Kick
Ice Punch
Return
Lopunny the Pokemon I wanted to base this team around. Its set is designed to hit hard and fast. Fake Out is obvious for setup while I'm not sure whether to use High Jump Kick or Drain Punch. High Jump Kick is riskier with Protect floating around but hits harder while Drain Punch is weaker but doesn't have to worry about Protect and heals you. Ice Punch for Landorus-T, Garchomp and Mega Salamence. Lastly Return for STAB.
Garchomp @ Lum Berry
Ability: Rough Skin
EVS: 252 Atk / 252 Spe / 4 HP
Nature: Jolly
Rock Slide
Dragon Claw
Earthquake
Protect
Garchomp another hard hitting physical attacker. Garchomp hits really hard while providing nice coverage. One problem is having to dodge Garchomp's Earthquakes. Rock Slide is for hitting Slow Ice Types and pokes like Arcanine and Volcarona. Dragon Claw for Stab and neutral coverage. Earthquake is for wrecking things Heatran and Mega Metagross while getting STAB. And Protect cause Protect.
Gengar @ Focus Sash
Ability: Levitate
EVS: 252 SpAtk / 252 Spe / 4 HP
Nature: Timid
Shadow Ball
Sludge Bomb
Will-O-Wisp
Protect
Gengar a Pokemon to dodge Garchomp's Earthquakes. This is the standard Gengar with Shadow Ball for STAB and hitting hard. Sludge Bomb is for Fairies and also gets STAB. Will-O-Wisp is for crippling Mega Kang and other Physical Attackers while Protect is just Protect to stall or avoid an attack.
Entei @ Leftovers
Ability: Pressure
EVS 252 HP / 236 Atk / 20 Spe
Nature: Adamant
Scared Fire
Iron Head
Protect
Stone Edge
Entei a tankier Pokemon to help with Garchomp and Azumarill. Entei is bulky and can hit hard back. Sacred Fire is for high hitting physical STAB damage on Grass and Ice Types it is the main move to use. Stone Edge is for Arcanine, Charizard and Talonflame. Iron Head hits fairies and opposing Rock Types like Tyranitar. Protect is ther to stop damage from EQ.
Azumarill @ Sitrus Berry
Ability: Huge Power
EVS 244 HP / 252 Atk / 12 Spe
Nature: Adamant
Play Rough
Belly Drum
Aqua Jet
Protect
Azumarill once setup hits super hard and that is what is awesome. Belly Drum is for setting up sweeping. Aqua Jet is the best move because it goes first and hits super hard with STAB. Play Rough is for Dragons and bulky dark types like Umbreon while Protect is to stall out a turn to make it safe to Belly Drum.
Magnezone @ Choice Specs
Ability: Magnet Pull
EVS 168 HP / 252 SpAtk / 88 Spe
Hidden Power Fire
Flash Cannon
Volt Switch
Thunderbolt
Magnezone is kind of interesting in VGC as not many people expect it. It hits super hard with Flash Cannon and Thunderbolt which are using on Pokemon like Talonflame and Azumarill. Hidden Power Fire roasts Ferrothorn and Scizor while Volt Switch lets it get out if it is in a bad situation like stuck with Garchomp or Mamoswine.
