Hi everyone. I decided to make a team and heard so much about the new core of Gallade-Mega and Bisharp + Rotom-W so here is my take on that. Share your thoughts

Gallade-Mega @ Galladite
Ability: Inner Focus
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Close Combat
- Zen Headbutt
- Substitute
The wallbreaker and set up sweeper. Gallade can perform well at the beginning middle and late game. all depends on the opponent's team. 110 speed puts him in great speed tier but it is still outsped by lots of old and new threats such as Greninja, has a lot of trouble against priority specially BB and really cannot allow himself to get burned or paralyzed. For those reasons Substitute is here replacing Knock Off from my previous set as Gallade's STAB's are usually enough to wallbreak or sweep as SD+165 base attack stat gives him insane power. MGallade finds many opportunities to set a Sub as the opponent is forced to make a switch into his MGallade's checks. Knock Off were used kind of as the same way by hitting checks on the switch and removing their item but after playing more with Sub it is better to use against many threats and it is more suited for those who are hoping to set up and make a sweep. I first started with Psycho Cut on this set, for the better accuracy, but Zen Headbutt is arguably better thanks to more power and 20% flinch chance+ not that bad 90 accuracy. Max ev's in attack and speed with jolly nature so MGallade can tie with other 110 speed tier mons.
Sub cannot always save MGallade and as I said, he really needs help against fast mons and priority users plus his famous counter- MSableye makes MGallade to switch the hell out so he also need some Fairy help.
For those things and more, here are the chosen partners:

Bisharp @ Life Orb
Ability: Defiant
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Sucker Punch
- Knock Off
- Iron Head
- Pursuit/ Aerial Ace
Great partner as both of them covers each other weaknesses and put great offensive pressure on the opponent. Bisharp traps Lati@s destroys Sylveon and Clefable with Iron Head and checks a lot of speedy mons with priority Sucker Punch. Knock Off provides even more offensive pressure by hitting very hard many Pokemon on the switch and removes their item. Defiant welcomes Intimidate users and makes Bisharp have a lot of fun time with sticky web teams.
Aerial Ace suggested by Uralya can work really great luring Chesnaught and Keldeo
Pursuit is still very good option to trap not only Lati@s but also low hp mon trying to switch out hoping for a better match up later.

Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 248 HP / 216 Def / 44 Spe
Bold Nature
IVs: 0 Atk
- Hydro Pump
- Will-O-Wisp
- Thunder Wave
- Volt Switch
Stops Talonflame checks Greninja spreads burns + T-Wave for support against fast mons or MCharizard-X so my MGallade can outspeed the opponent later. Volt switch helps a lot after that to gain momentum. Pain Split can be missed sometimes but T-Wave is really good for MGallade that can make the difference in many match ups and I usually finds it way more helpful on this team. Will-O-Wisp is still here to spread burns on non-fire type physical offensive threats.

Latias @ Life Orb
Ability: Levitate
EVs: 72 HP / 184 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Draco Meteor
- Psyshock
- Healing Wish
- Defog
Bulky Defogger when I find the need to remove hazards but mainly exist in this team to use Healing Wish and give a teammate another chance to battle. this thing allows me to heal MGallade and Bisharp if they got burned or paralyzed . allows me to heal Rotom-W and open for me the option to run T-Wave instead of the unreliable Pain Split, and so on. Its just feel mandatory to have her in this team but thats not all. Psyshock and Draco Meteor are very helpful to hit some dragons checks and Fighting types.

Landorus-Therian @ Leftovers
Ability: Intimidate
EVs: 252 HP / 240 Def / 8 SpD / 8 Spe
Impish Nature
- Stone Edge
- Earthquake
- Stealth Rock
- U-turn
Lando creates together with Rotom-W the great Volt-Turn core which can help a lot to prepare the ground for my sweepers and wall-breakers. Lando also provides the much needed Stealth Rock to support the team, making lots of nice OHKO's instead of 2HKO's (+2 252 Atk Gallade Close Combat vs. 4 HP / 0 Def Latios: 282-332 (93.3 - 109.9%) -- guaranteed OHKO after Stealth Rock) Stone Edge is for Talonflame mainly ( and NoGuard MPidgeot lol ) but also can be used to hit as hard as possible levitate and flying targets. Intimidate is wonderful for my team to force fast physical threats out. 8 speed ev's are for out-speeding standard Rotom-W to scout with U-Turn if needed and Magnezone. 8 ev's on SpD prevent being OHKO'd by MegaMan's HP Ice at full hp

Clefable @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 160 Def / 96 SpD
Calm Nature
IVs: 0 Atk
- Moonblast
- Soft-Boiled
- Calm Mind
- Flamethrower
The Special sweeper , The answer to MSableye The burns and toxics absorber.. Clefable is one of the top partners MGallade can have as she can do all that and more-Flamethrower gives a source of Fire move for my team to deal with Ferrothorn. EV's were changed in order to prevent being 2HKO'd by some key threats, as Uralya suggested me, with Calm nature such as Hydro Pump Greninja. Clefable works also great for dealing with Latios, which can make the loss of Knock Off on MGallade and Pursuit on Bisharp, if I am going for Ariel Ace, less painful.
