Hi it's my first rmt, it's been a while since I started playing gen7ou and I experimented all sort of things and I'm starting to wander how good I currently am at teambuilding in this tier.
For this team I wanted to build a psyspam on gallade-mega because I thougt it could be fun and gallade is one of my favorite mon in the license.
Galladite
Justified
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
Close Combat
Zen Headbutt
Knock Off
Swords Dance
Gallade is obviously the first mon of this team he has a good speed tier of 110 wich allow him to outspped the majority of the non scarf metagame his he can also force defensive mon to switch out because he can often deal over 50% damage with his close combat generaly that mean he has a free koff or a free sd. Zen headbutt is boosted under psychic terrain wich allow it to hit hard against defensive mon who aren't weak to close combat.
Fightinium Z
Psychic Surge
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
Psychic
Moonblast
Focus Blast
hidden power fire
Tapu lele is the psychic terrain setter
(the only one in the tier) his access offer a boost of 50% to psychic type moves wich mean he can deal a lot a damage even if he's not specs, I chose the fightinium z version because it can lure heatran and ferrothorn and ko them after a psychic . Psychic terrain also immune against mon who rely on their priority like azumarill, he's access to hp fire allow him to deal a lot of damage against scizor-m who is normally a check to lele.
Choice scarf
Beast Boost
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
Leaf Blade
Sacred Sword
Smart Strike
Knock Off
Kartana is one of my favorite pokemon in the meta even though I think the one who made him wasn't in this right mind when He design his stats. Kartana has a speed of 109 wich is really good the scarf allow his to be a good revenge killer and late game sweeper, he also give more speed control to the team. His move can cover a lot of mon but he will have trouble to deal against the opposing team in early because he will have a lot of counters/checks, he also have a reallt low spe def wich will make him have trouble against special attacker he can't ohko, the biggest threat for him are greninja if he has battle bond and kill one mon because his priority wil have a good chance to ohko kartana if his low. Katana is also weak to himself sice if he is lock on leaf blade or smart strike it will be a free switch for the opposing kartana who will have a free knock off.
Assault Vest
Ability: Soul-Heart
EVs: 248 HP / 224 SpD / 36 Spe
Sassy Nature
Volt Switch
Fleur Cannon
Focus Blast
Iron Head
Magearna is here with the assault vest because the team has a serious problem with special attacker his bulk allow him to easyly take any special attack and pivot on them he also help the team to deal with mon like serperior and greninja who are hard to deal depending of their set it also help against other psyspam by walling alakazam-m and lele to force them out and pivot on the opponent mon.
Leftovers
Intimidate
EVs: 252 HP / 112 Def / 144 Spe
Impish Nature
Stealth Rock
Earthquake
Hidden Power [Ice]
U-turn
Do I really have to introduce him? 1st of all the ou usage since gen6 here is landorus therian. This time it will be he's defensive variant that I'll be using he is a good pivot against a lot of physical attacker thanks to intimidate who will lower by one the attack of it's opponent he is the check of all the ground type attack or other landorus, he can place the sr, it's access to hp ice allow him to beat other landorusby puting them mid life then he can u-turn he also soften the matchup against charizard-x since he lower his attack and deal a lot of damage with earthquake.
Leftovers
Levitate
EVs: 252 HP / 200 Def / 56 Spe
Bold Nature
Hydro Pump
Volt Switch
Will-O-Wisp
Defog
The last one of the team is rotom, he is the defog of the team. He is here to soften the rain matcup since the it's everywhere and can be hard to deal with, he is able to switch in into swampert to wow him and reduce his firepower. His access to volt switch allow him to pivot on the opponent switch in. He will have a good time against most of the physical attacker since he can burn them wich will reduce their power.
TRHEAT LIST
Greninja is a hard mon to deal with in this team since it doesn't have anithing to restore hp so once magearna is low hp he can become a hard mon to deal with the only thing you can do against him is to play with magearna or rotom, if he had a kill you'll have to revenge kill him with kartana while taking care of his priority with the psychic terrain.
This guy I
hate him he has an insanely good matchup against this team, to play against him you'll have to have an healthy rotom so when he wil active his ability you'll be able to wow him. The other thing you can do is playing arround the terrain he need to activate his seed with lele who will change the terrain. If hawlucha need psychic terrain you'll have to win with rotom.
Charizard-y isn't a big threat since the only thing you have to do is revenge kill him with gallade but he can do insane damage to the team before that so you'll have to always have thr sr on because he take 50% of his life on them.
That's all for the team if you have any suggestion to make the team better you're free to tell them.
Sorry if my english isn't really good it isn't my native language.
