Everyone likes this little lioness pokemon. Unfortunately, he is doomed to UU because of poor speed, and limited options for his incredible attack. People let's give him another try! Think outside the box for a change. I now would like to introduce bulky Luxray!
Luxray @ Leftovers / Chesto Berry
Ability: Intimidate
Nature: Bold
EVs: 204 HP / 252 Defense / 52 Special Attack
*Thunderbolt
*Thunderwave
*Hidden Power [Ice] / Light Screen / Roar / Rest / Protect
*Light Screen / Roar / Rest / Protect / Sleep Talk / Substitute / Toxic
Geez this thing has support move options out the wazoo!
Now to start, Luxray has incredible base stats, but people need to accept that he is never going to make it as a sweeper in OU. He lacks the speed, and physical movepool. As discussed with Electivire, Thunderbolt will always do more than Thunderpunch / Spark / Thunderfang do to higher base power. Luxray has a decent 95 base special attack to work with, so thunderbolt is by no means a bad option on him.
Now to discuss the moveset. The EVs give him 352 HP, his highest leftovers mark, and a whoping 282 defense paired with Intimidate. He also will have 239 special attack, which is not impressive, but will allow him to do some damage if he has to, and kill what an electric type is supposed to kill. Thunderwave is a must on Luxray as this thing is made to switch in and intimidate sweepers, and can cripple the opponents team with paralysis. For the other options... Take your pick! He can absorb status with resttalk, lead and use protect for scouting and gain lefties recovery, roar can help with SR and help you shuffle paralysis, Light Screen can help your team and cover the other base (gives him 388 Special Defense), and Toxic can really wear down something like Cresselia if you have trouble with it.
Hidden Power [Ice] seems like a gimmick on a special attack of 239, but will allow Luxray to counter Garchomp. What?????? An Electric type countering Garchomp? Yup... Lets see how luxray fairs against the heavy hitters of OU:
Damage Calcs Please:
DD Dragonite Outrage (Intimidate nullifying DD) 36.36-42.9%
DD Dragonite Outrage (Intimidate nullifying DD) w/ Life Orb 47.16-55.68%
DD Dragonite Earthquake (Intimidate nullifying DD) 40.63-47.73%
DD Dragonite Earthquake (Intimidate nullifying DD) w/ Life Orb 52.84-61.93
Bulky Gyarados Earthquake (Intimidate nullifyng DD) 35.51-41.76%
DD Gyarados Earthquake (Intimidate nullifying DD) w/ Life Orb 55.11-64.77
Choice Scarf Garchomp Outrage (Intimidate, -1 Attack) 26.14-30.97%
Choice Band Heracross Close Combat / Megahorn (Intimidate nullifying CB) 37.78-44.6%
Choice Scarf Heracross Close Combat / Megahorn (Intimidate, -1 Attack) 25.57-30.11%
Swords Dance Lucario Close Combat (Intimidate, +1 Attack) w/ Life Orb
59.94-70.45%
Choice Band Metagross Meteor Mash (No Intimidate) 32.95-38.92%
Swords Dance Scizor Quick Attack (Intimidate, +1 Attack) w/ Life Orb
15.34-18.18%
Swords Dance Scizor Brick Break (Intimidate, +1 Attack) w/ Life Orb
28.13-33.24%
Choice Band Tyranitar Crunch (Intimidate nullifying CB) 26.7-31.5%
Choice Band Tyranitar Stone-Edge (Intimidate nullifying CB) 33.24-39.2%
DD Tyranitar Earthquake (Intimidate nullifying DD) 40.63-47.73%
Choice Band Weavile Ice Punch (Intimidate nullifying CB) 21.31-25%
Swords Dance Weavile Ice Punch (Intimidate, +1 Attack) 28-33.24%
To put it simply this thing is bulky. Now, what to do with all that bulk... T-wave effectively screws quite a bit of these pokemon. DD Gyarados may try to pwn you with Earthquake, only to be OHKOed. Lucario's Close Combat hurts, but you can T-wave him on the revenge and make your team eat Extremespeeds instead of Close Combats, or you can just finish him off thanks to life orb recoil and defense drops. You may not want to activate Heracross' Guts, but T-wave kind of screws over the Scarf version.
As for Garchomp:
Bulky Luxray Hidden Power Ice vs. Garchomp: 64.43-75.91%
May seem kind of pathetic, but if you switch in on Garchomp's Outrage, you beat him, plain and simple. Your opponent will have to pray that Outrage doesnt last 3 turns...
So the strategy is... to use Luxray as a physical wall and stop mighty physical sweepers from running through your team. If you can catch them early, luxray can screw up their sweep.
