This is battle single stadiums, I'm assuming. Unfortunately, with the DLC arriving, almost all of your pokyemans in this team have been yeeted to irrelevancy. Mimikyu is an amazing pick, there is no denying that. Tyranitar is quite solid, however, you MUST run a physical tyranitar as special tyranitar...kinda sucks. Unfortunately, the rest of your Pokemon....are not good anymore. First, Arcanine is outclassed by landorus therian, a superior user of intimidate. Therefore, you should always use landorus over arcanine. I'm assuming you want a defensive offensive hybrid like arcanine, or basically, a bulky attacker. Now, I'm going to use sitrus berry purely because of assault vest blocking ze rocks.
Landorus-Therian @ Sitrus Berry
Level: 50
Ability: Intimidate
EVs: 252 HP / 252 Def / 4 SpD
IVs: 30 Spe
Impish Nature
- Earthquake
- Rock Tomb
- U-turn
- Stealth Rock
Pretty standard defensive Landorus Set. E quake is stab, rock tomb is coverage, u-turn is for momentum, and rocks are...rocks. 30 Spe IVs are for outslowing other landorus.
Next, rotom mow is outclassed as a special attacker by dragapult.
Dragapult @ Life Orb
Level: 50
Ability: Infiltrator
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Draco Meteor
- Shadow Ball
- Thunderbolt
- Fire Blast
Dragapult is a kewl pokeymans. Draco meteor is powerful stab, shadow ball is also powerful stab, thunderbolt is coverage to dent water and flying types (other than lando lel) and fire blast is to nuke grass types like kartana and ferrothorn, although kartana will die to any special attack anyways lel
Hydreigon is another special attacker, however I think you need a physical attacker, so I'm going to suggest urshifu.
Urshifu @ Choice Band
Level: 50
Ability: Unseen Fist
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Wicked Blow
- Close Combat
- Sucker Punch
- Thunder Punch
Banded Urshifu is pretty simple. Two stabs, sucker punch to revenge kill things, and thunder punch for water and flying types too.
Corviknight, surprisingly, isn't that good. Toxapex is much better.
Toxapex @ Black Sludge
Level: 50
Ability: Regenerator
EVs: 252 HP / 252 SpD / 4 Def
Calm Nature
- Scald
- Recover
- Haze
- Toxic
Standard Pex set. I...dont know what to say lel. Uhh, scald is for burns, recover is recovery, haze is for stat boosts to commit die and toxic is good damage output.
Now, Tyranitar's new set.
Tyranitar @ Weakness Policy
Level: 50
Ability: Sand Stream
EVs: 252 HP / 252 Atk / 4 Spe
Adamant Nature
- Stone Edge
- Crunch
- Earthquake
- Ice Punch
Pretty simple again. Stone edge is stab, crunch is also stab, e quake nails dem annoying rock types and steel types and ice punch dents ground and flying pokeymans.
Finally, an edited kyu set.
Mimikyu @ Life Orb
Level: 50
Ability: Disguise
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Play Rough
- Shadow Sneak
- Phantom Force
Mimikyu is insane in bss. Swords dance is good offensive pressure, play rough is stab, shadow sneak is for revenge killing and phantom force is good stab.
