Here, let’s try to fix one of my favorite mons: Luxray.
First of all, he’s Electric/Dark now. This gives him 3 new weaknesses, but 4 new resistances and an immunity to psychic. It also gives him STAB crunch as a better option for reliable physical damage.
Luxray’s whole deal is that he can see through walls to hunt his prey, so I gave him a new ability to reflect this:
Gleam Eyes: STAB attacks never miss and have a 1/3 chance to paralyze the target.
This means that all STAB moves, not just Electric ones, have a paralyze chance. It’d be cool to have this stack with the innate paralyze chance of a lot of Electric moves.
So now Luxray has a paralyzing crunch, but what else can we do to make him better? Well, his stats.
523’s not a bad BST, it just needs to be shuffled around a bit. I took 40 points from his Special Attack and giving them out to his other stats. I put 20 into speed, and give 10 to each defense stat, giving Luxray:
80 HP
120 Atk
89 Def
55 Sp. Atk
89 Sp. Def
90 Spd
I don’t know much about competitive Pokémon, but this should make Luxray a better mon. Maybe? I don’t know.
Edit: If we’re not doing drastic stat redistributions, you can just buff his speed by 20 or something.
