2021? Victini Moveset? Well I'm crazy as you see.
Sun Sweeper
Victini @ Life Orb
Ability: Victory Star
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Solar Beam
- Blue Flare
- U-turn / Psyshock
- Thunder Wave / Focus Blast
Solar Beam - Obviously, Sun team.
Blue Flare - STAB; Blue Flare going crispy with Victini's Type, Sp.Atk + Sun Boost.
U-Turn/Psyshock - Scouting; specially if foe has Cloud Nine or other weather-setting moves or take care of those annoying Poison-types with high sp.def; as well as criple Blissey/Chansey who would attempt to wall this set.
Thunder Wave/Focus Blast - Use something unexpected and cripple their revenge attempts or kick heatran out of the room.
Staller? Why? Sounds unique tho.
Victini @ Flame Orb / Grip Claw
Ability: Victory Star
EVs: 164 HP / 172 Def / 172 SpD
Timid Nature
- Toxic / Trick
- Fire Spin
- Taunt / Protect
- Encore / Trick
Toxic/Trick - Why not? Doesn't stalling require a glorious move such as this? If you're using Trick--better mind they WONT get burned and POISONED at the same time; so it's your choice. You could also Trick back the flame orb tho; but that would make them evade your victini/take it out with water types.
Fire Spin - Lock them from switching as well as damage them for a few turns... hehehe... Grip Claw makes it further more ANNOYING.
Taunt/Protect - Why would you let them taunt you? Why would you let them hurt you?
Encore/Trick - If your enemy is trying to use slow Pokemon to set-up; they're surely gonna have a VERY bad time; using Taunt will also FORCE THEM to use struggle for a few turns, further increasing your sadistic level. If you're using Flame Orb--Trick should do for the first move; to make them taste burns ofcourse.
Purpose of your stalling is to move FIRST as giving them status conditions or trapping them IS your priority, which is why I recommended Timid nature, tho you can use whatever you wanted. Victini's bulk is decent, tho the typing has Rock, Water, Ground, Dark and Ghost as weaknesses which is annoying.
The funny part is when you're using Flame Orb and the dude trades their scarf (since that's an infamous strategy, tried, tested & trusted™) with it. It does do a lose-lose situation, but the guy got burned, and if it's a physical sweeper--that WOULD be EVEN MORE FUNNY. LMAO. Some also attempts to use thief on Victini (it's super effective and think that they might steal an important item from your victini); but they realized they didn't steal leftovers or lum berry--they stole a flame orb, your quote will be "All yours, partner." as they get burnt up.
The first move you should use is either Fire Spin (lock them down lmao) or Toxic.
I know it's risky to use stalling victini; but they just won't expect such a surprise.
The sun sweeper set is a standard, so nah no talks about it.
