OK, my first team was awesome, but I've decided to make it even better, because it honestly, it had trouble with Azumarill and other bulky Water-Types, but this time shall be different!!! (Maybe) :I
Greninja @ Life Orb
Ability: Protean
EVs: 252 SpAtk/ 252 Spe/ 4 HP
Timid Nature
-Surf
-Dark Pulse
-Ice Beam
-Grass Knot
This Greninja is the same except I gave it Grass Knot to hit bulky Water-Types who would otherwise wall this set. With Dark Pulse, it can hit Aegislash hard. Surf is for hitting Charizard and other Fire/ Rock types. Ice Beam hits Dragons and Grass types. Max SpAtk and Spe with Timid Nature makes sure Greninja hits and fast. Protean makes him hit that much harder.
Lucario @ Lucarionite
Ability: Inner Focus
EVs: 252 Atk/ 252 Spe/ 4 HP
Adamant Nature
-Close Combat
-Bullet Punch
-Crunch
-Swords Dance
Lucario is still the same because he didn't need any changes, and he covers Steel-Types and Fairy-Types that wall Greninja. Close Combat is the main STAB, and after Lucario goes Mega, it HURTS. Bullet Punch over ExtremeSpeed because the latter doesn't hit Fairy-Types super-effectively. Crunch hits Aegislash and other Ghost-types. Swords Dance with Max Atk and Spe makes sure Lucario can KO Florges after a Swords Dance and outspeed Azumarill's Aqua Jet using Bullet Punch.
Galvantula @ Focus Sash
Ability: Compoundeyes
EVs: 252 SpAtk/ 252 Spe/ 4 SpDef
Timid Nature
-Thunder
-Bug Buzz
-Energy Ball
-Sticky Web
Galvantula serves a dual-purpose on my: set-up Sticky Web and KO/ weaken Pokemon that threaten the rest of my team. Thunder gets an accuracy boost from Compoundeyes and STAB, and along with Bug Buzz and Energy Ball, hits a lot of Pokemon for Neutral coverage. Sticky Web slows down grounded Pokemon and nerfs Scarfers. Max Spe and Focus Sash makes sure that Sticky Web gets up and max SpAtk makes sure Galvantula leaves a dent in anything it hits.
Swampert @ Rindo Berry
Ability: Torrent
EVs: 240 HP/ 252 Atk/ 16 Def
Adamant Nature
-Earthquake
-Waterfall
-Toxic
-Roar
After Sticky Web is set up, Swampert is free to come in and Roar/ Toxic-stall to its hearts content. Max Atk Earthquake hits Tyranitar and Aggron and Waterfall hits everything else. Near max HP and Def investment makes Swampert able to take lots of hits and Rindo Berry makes Swampert able to survive at least one hit from a Grass type.
Rotom-Wash @ Lum Berry
Ability: Levitate
EVs: 248 HP / 28 SpAtk/ 232 SpDef
Calm Nature
-Discharge
-Hydro Pump
-Will-O-Wisp
-Confuse Ray
Triple Status Rotom-Wash is awesome. Discharge is STAB and causes Paralysis, Will-O-Wisp cripples physical attackers. Confuse Ray forces switches, and Hydro Pump is STAB with lots of power. Calm Nature and EVs in HP, SpDef makes Rotom-W into a Special Defensive beast. Lum Berry makes sure Rotom doesn't get crippled by statuses.
Forretress @ Leftovers
Ability: Sturdy
EVs: 252 HP/ 252 Def/ 4 SpDef
Relaxed Nature
-Gyro Ball
-Stealth Rock
-Spikes
-Rapid Spin
Physical Wall Forretress. With max HP and Def AND Leftovers, Forretress is sure to set up on at least one of his hazards, further pressuring. Gyro Ball hits fast Pokemon hard and Stealth Rock is the hazard for those Pokemon that aren't affected by Sticky Web. Spikes puts even further pressure on grounded Pokemon and Rapid Spin gets rid of opposing hazards.
Overall, this team has awesome synergy and with all the help of their partners, Lucario and Greninja have an easy time tearing thru a lot of teams.
