The Team






=======================================================

Mesprit @ Lum Berry
Ability: Levitate
Evs: 4HP /252Satk /252Spd
Nature: Timid
Psychic
Grass Knot
Thunder Wave
Stealth Rock
Description: I pick mesprit because he have a decent speed, natural bulk, good offensive stats and capable of using stealth rock. He have a good matchup with most lead and after he setup the rocks he is capable of hurting the enemy, not like uxie
Moveset: Psychic is for STAB. Grass Knot for Omastar, Cloyster, Rhyperior, etc. T-wave and Stealth Rock are for team support
Nature, Evs and item: Its simple, nature and evs is for max Spd and Satk. Lum Berry is specially for beating scarf vena lead, jumpluff and the uncommon venomoth

Ninetales @ Leftovers
Ability: Flash Fire
Evs: 36HP /252Satk /220Spd
Nature: Timid
Flamethrower/ Fireblast
Energy Ball
Hidden Power (Rock)
Calm Mind
Description: At first look ninetales can be seen completly outclassed by houndoom, but thats not close too be the thruth. Ninetales have a better bulk and superior speed, which make her a good counter for all the other fire types (including Houndoom) who can cause problem too this team
Moveset: Calm Mind is for increasing my power and also help me too take better hits on the special side, after 2 calm mind a Surf from the standard Milotic only take like 30% and i can 2HKO back with energy ball. Flamethrower/Fireblast are for STAB and Energy Ball and HP (Rock) is for coverage
Nature, Evs and item: Tmid nature with 220 allow to outspeed max speed base 95. Max Satk to hit harder and the other in HP for increasing Ninetales bulkyness. Leftovers is for increase of survivality

Rhyperior@ Leftovers
Ability: Rock Solid
Evs: 134HP /252Atk /38Def /84 Spd
Nature: Adamant
Rock Slide
Earthquake
Substitute
Megahorn
Description: This is a variation form the standar Su(b)perior with a little change from the evs. Rhyperior is capable of setup a sub so many times than is not even funny, behind a sub alot of his counters have high changes of end fainted, like torterra, slowbro and tangrowth. He can dismantle unprared stall team all by himself, his only real counter is defensive milotic.
Moveset: Rock Slide and Earthquake, Rock Slide over Stone Edge to avoid being setup fodder for substall moltres and substall articuno, the less power never represent a big issue. Megahorn is for coverage and substitute is for obvious reason
Nature, Evs and item: 134 HP is for 101HP subs. Adamant + max atk is for hiting really hard. 84 spd is for outspeeding minimun speed base 50, like registell, chansey and tangrowth. 38 def is for receiving better iron heads from registeel. Leftovers is for recovering health after using a sub

Toxicroak @ Leftovers
Ability: Dry Skin
Evs: 42HP /252atk /216Spd
Nature: Jolly
Focus Punch
Ice Punch
Substitue
Sucker Punch
Description: I pick toxicroak because his great typing and amazing ability, he is almost a full stop to rain dance team. With his typing and abilty he can setup sub rather easily, and start hiting hard everything ballsy enought to come in. He have the only priority of this team so i have to save him until late game just in case some fast sweeper like swellow start giving me troubles
Moveset: Is a really standar subpunch croak, focus punch for huge base power combined with STAB, sub for avoid hits and use the FP, ice punch for coverage and sucker punch for priority. One note, STAB focus punch hit harder than a superefective ice punch
Nature, Evs and item: Jolly nature with 216 spd ev is for outspeeding max speed base 80, like offensive venasaur, 252 atk is for increase the damage given and 42HP is for more bulkyness. Leftovers is for recover healt taken from the subs

Calm Mind
Description: Mismagius is here because he is capable of seting up in the face of all the haze less milotic who gives alot of troubles to this team. i didnt pick rotom because his inferior speed and bulk and with that make my team more vulnerable to other mismagius
Moveset: Sub and CM is for the mismagius setup, Shadow Ball is for STAB and Thunderbolt to hit milotic harder and because HP (fighting) make me lose an import speed point
Nature, Evs and item: Timid 252 speed is for outspeeding all the HP (fighting) mismagius and to atleast speed tiying with the other max spd base 105 like scyther. Max Satk to hit harder

Exeggutor @ Leftovers
Ability: Clorophyll
Evs: 44HP /252Satk /212Spd
Nature: Modest
Psychic
Leaf Storm

Leech Seed
Description: Why this thing is not uu?. This thing hit like a truck from the special side, have good couple of resistance combined with a good physical defense. He is capable of OHKO a good part of the metagame, he also can suppot the team with sleep powder and leech seed, his only letdown is his speed.
Moveset: Psychic and Leaf Storm is for STAB, Sleep powder is to put something to sleep, specially his counter on the swtich, and leech seed allows to exxegutor to beat 2 of his biggest counter (registeel and chansey) in a 1on1
Nature, Evs and item: Modest nature with 252Satk is for make good use of his 125 base Satk, 212spd is for outspeeding minimun speed base 81 by 1 point and the other evs in HP
