Luxray is meant to be a stallbreaker in this meta but, with it's stats, perhaps it could be a nice mixed attacker. Though, it's movepool isn't the greatest, maybe it can improved by my own imagination like a child wanting more.
Luxray @ Life Orb Electric &
Dark
Ability: Intimidate
EVs: 116 Atk / 216 SpA / 176 Spe or 335 Attack / 280 Special Attack / 220 Speed
Lonely Nature
-
Flare Blitz
-
Ice Beam
- Crunch
- Volt Switch
Everything points to this pokemon looking like it should have dark typing, it's design, the fact that it knows the move "crunch", etc. That part is easy enough to understand, the flare blitz/ice beam part might not be so understandable though. Electricity is essentially made of hot & cold particles creating friction, also when something gets electrocuted it either catches fire or has extreme burn marks. Darkness is often associated with "hell" in which is told to be extremely fiery. Darkness is also associated with "death" which is told be very cold. Pretty cheeky of me, eh?
Aside from that though, here are some random calcs:
216 SpA Life Orb Luxray Volt Switch vs. 0 HP / 4 SpD Simipour: 338-400 (116.1 - 137.4%) -- guaranteed OHKO
116+ Atk Life Orb Luxray Crunch vs. 0 HP / 0 Def Mr. Mime: 226-266 (102.2 - 120.3%) -- guaranteed OHKO
216 SpA Life Orb Luxray Ice Beam vs. 0 HP / 0 SpD Simisage: 291-343 (100 - 117.8%) -- guaranteed OHKO
216 SpA Life Orb Luxray Volt Switch vs. 192 HP / 0 SpD Poliwrath: 257-304 (69.6 - 82.3%) -- guaranteed 2HKO
The EV spread may look weird yet, it might work. I gave Luxray 176 EVs in speed so that it can outspeed a good amount of the slow meta. I gave it "lonely" nature so that it's special defense doesn't get lowered & the lowering of the defense can easily be fixed with it's ability "intimidate". I chose "volt switch" over "thunderbolt" as it's STAB as "thunderbolt" doesn't do that much more & "volt switch" is great for momentum & even if a ground type comes in on the predicted "volt switch", Luxray still has "ice beam" to hit the incoming ground type.
216 SpA Life Orb Luxray Ice Beam vs. 0 HP / 0 SpD Torterra: 458-541 (138.3 - 163.4%) -- guaranteed OHKO
This Luxray can even take on Pawniard:
116+ Atk Life Orb Luxray Flare Blitz vs. 0 HP / 4 Def Eviolite Pawniard: 283-335 (122.5 - 145%) -- guaranteed OHKO
252+ Atk Pawniard Sucker Punch vs. 0 HP / 0- Def Luxray: 72-86 (23.9 - 28.5%) -- 97.3% chance to 4HKO
(Luxray would be left with around 115 HP after hitting with Flare Blitz)
And here's the calc for if Pawniard gets the "defiant" boost off of "intimidate":
+1 252+ Atk Pawniard Sucker Punch vs. 0 HP / 0- Def Luxray: 109-129 (36.2 - 42.8%) -- guaranteed 3HKO
(Luxray would be left with around 76 HP after hitting with Flare Blitz)
This set is by know means "broken" either, as fast hard hitting pokemon or pokemon like, Machoke, can knock it out rather easily. I feel this set would bring Luxray to A- rank.
