After BluBirD252 mentioned Espeon Screens Hyper Offense, I was inspired to make my own version of such a team, so I want to thank them first. Screens don´t benefit Weavile specifically that much as they don´t really cure it of its Keldeo/Scizor allergy, but I thought everybody´s favorite weaselly assassin could patch up a hole or two on this team.
Screens Hyper Offense
Brief(?) team building process:
Even screens Hyper Offense should pack a stealth rock setter, just in case. I think Landorus-Therian is generally the better fit over Garchomp, because it compresses more defensive utility and can also easily come in later in the game, if necessary. I originally wanted to run a suicide lead with Life orb and Explosion, but abstained after I realized that it´s defensive role was too valuable. It´s still a brutally offensive set, however. Expert Belt and the SpAtk investment allow it to knock out opposing Naive Landori, as well as Naive Garchomp and physically defensive Gliscor. The team´s standard lead, though it should be played a little more conservatively against rain teams. If you think the opponent is going to do something funny like setting up stealth rock themselves, simply U-turn into...
Screens setter. Denies opposing passive Pokemon such as Skarmory or Ferrothorn their own utility. It can also come in handy in a pinch to revenge kill a non-scarf Keldeo. Baton Pass allows it to escape from Tyranitar and Scizor without harm. Should optimally lead against rain teams.
Keldeo takes advantage of the fact that after a Light screen and a Calm mind boost, Rotom-Wash´s Volt Switch can no longer break its substitute. Sweeps mercilessly, if you can get 3 Calm mind boosts. Secret Sword + Hp Ghost gives it perfect coverage. It is supposed to trample over sand balance cores mainly, but can do ruinous damage almost every match.
I wanted to insert something funny in case an opponent tries to pursuit-trap Espeon. I originally wanted to go with Lucario, to make sure I had a different idea from BluBirD252, but the Jackal sadly lacks the space in his movepool to fit all the moves to reliably break PsySpikes cores, so I hope the pre-poster doesn´t mind. Substitute + Swords Dance allows it to effectively wallbreak, when Stone edge doesn´t miss. As mentioned, try to optimally get it in with Espeon´s Baton Pass on a Tyranitar Pursuit.
Weavile the Assassin patches up the team´s weakness to Dragon type sweepers and Alakazam. Fake out allows it to effectively come out on top of Focus Sash Alakazam (though a certain fellow player steadfastly insists that it could backfire, in case Alakazam chooses Inner Focus as its ability), and can also come in handy against weakened Volcaronas and Cloysters that have spun out of control. Muscle Band is the item of choice, as Weavile despises Life Orb recoil, and the Band is enough to guarantee the one-hit KO on Volcarona after stealth rock damage.
Haxorus is a lousy and pathetic excuse for a Pokemon that should be dropped to the bottom of the tier list if it is ranked at all, so that only I use it my preciousssss...
Haxorus is a Dragon Dancer that can sometimes claim the spoils of war by itself against rain teams, and in my humble opinion profits quite nicely from double screens to protect it from being revenge killed before it spirals out of control with Dragon Dance. Taunt gives it valuable set-up opportunities against Encore Politoed, Jellicent, Rotom-Wash and Skarmory. The Lum Berry gives an insurance against scald burns. The speed EV´s guarantee outspeeding scarfed Latios after two dances. +1 Outrage claims the one-hit KO against specially defensive Politoed as well as standard Rain abusers Keldeo and Thundurus-Therian, and Low Kick has a good chance to do the same to specially defensive Ferrothorn. Unnerve is chosen over Mold Breaker, as there are few abilities to bypass with that movepool; Skarmory and Forretress are too durable to drop in one hit without fire attacks, and all Levitate users except the very rare Bronzong also cave to Outrage instead of Earthquake.
Anyway, now that you have read that, don´t use Haxorus.
If you don´t suffer from ADHD like me and actually read through all that, thank you so much for your attention. Feel free to have a good laugh and (whispers) maybe even a really serious look at this team. Have a nice day, everyone, and stay healthy!
