One Glance of the Team before moving on:
(Bold is the new changes)
Gyarados@Leftovers
Adamant Nature
Ability: Intimidate
EVs: 156 HP, 72 Atk, 96 Def, 184 Spe
-Dragon Dance
-Taunt
-Stone Edge
-Waterfall
My Lead of all Leads, I choose it because it can fool those guys of using Electric-types on Gyarados but in mistakenly giving Electivire a free Motor Drive and Electivire returning the favor with Earthquake. I went with Taunt so the supporters, stalls, and sweepers stop powering up keeping my team alive bit longer. Ice Fang instead of Earthquake or Stone Edge so I can deal those Dragons and Flying. Waterfall is it's reliable STAB move.
SeaSlug (Gastrodon) @ Leftovers
Calm Nature
Ability: Storm Drain
EVs:252 HP / 4 Sp.Atk / 252 Sp.Def
-Ice Beam
-Recover
-Toxic
-Earth Power
Rotom (Wash)@Leftovers
Modest Nature
Ability: Levitate
EVs: 112 HP, 252 SpA, 144 Spe
-Will-O-Wisp
-Hydro Pump
-Thunderbolt
-Pain Split
I love Rotom-W that he can wear down the enemy with Will-O-Wisp, bring pain with its two STAB moves, and recover with Pain Split.
Jellicent@ Leftovers
Bold Nature
Ability: Cursed Body/Water Absorb
EVs: 248 HP, 216 Def, 44 Spe
-Scald
-Will-O-Wisp
-Recover
-Taunt
D-Slayer(Heatran)@Choice Scarf
Modest/Timid Nature
Ability:Flash Fire
EVs: 4 HP, 252 SpA, 252 Spe
-Overheat
-Dragon Pulse
-Hidden Power Rock
-Earth Power
Heatran is a Dragon Slayer because his moveset can get rid of Dragon-types with Dragon Pulse and HP Ice. Earth Power to counter other Fire-types. Overheat can revenge kill or sweep the opponent.
Ferrothorn@Leftovers
Sassy Nature
Ability:Iron Barbs
EVs: 252 HP, 4 Atk, 252 SpD
-Curse
-Gyro Ball
-Power Whip
-Leech Seed
Ferrothorn is the definition of torture chamber. First, Ferrothorn sets up with multiple Curses to slow him down while powering up his Attack and Defense making him more of a tank. Pull of a Leech Seed to start the torture, then go for the attack with his two STAB moves.
