HP 73->78
Atk 76->61
Def 75->80
SpA 81->116
SpD 100->110
Spe 100->110
BST 505->555
Reasoning: As the feminine counterpart to Arcanine, it always severely bothered me that Ninetales's stats were so mediocre. So, I increased the BST to match Arcanine's: 555.

====053 persian
====Type Normal/Dark
====Atk 70->85
====BST 460->475
====Reasoning: Persian's STAB Special movepool barely existed, so I gave it a nonzero amount of physical offense to match.

264 linoone
SpA 50->85
Spe 100->105
BST 435->475
Reasoning: Linoone has a kinda silly Special movepool.

277 swellow
HP 70->60
Atk 100->120
Def 60->50
BST 455->455
Ability 1: Unburden->Guts
Reasoning: A less extreme version of my changes to Swellow in my Fire Red Omega run.

292 shedinja
Atk 90->115
Spe 40->85
BST 236->306
Reasoning: Despite having Wonder Guard, Shedinja was pathetic, and really needed buffs.

Def 40->60
SpA 85->105
SpD 75->85
Spe 95->110
BST 405->515
Reasoning: ...really, Drayano? You just left Plusle and Minun to suffer?

Atk 40->60
Def 50->80
SpA 75->85
SpD 85->105
Spe 95->110
BST 405->515
Reasoning: See above.

327 spinda
All 80->85
BST 480->510
Reasoning: I felt like Spinda still needed a bit more of a buff.

330 flygon
HP 80->85
Def 75->85
SpD 75->85
Spe 100->110
BST 550->585
Reasoning: I felt like Flygon and Altaria got gypped in the stat department, given their status as dragons. I was initially going to boost them both all the way to 600, but I held off a little.

334 altaria

Def 90->105
SpA 100->110

====Def 70->85
====SpA 100->90
====SpD 90->110

====Reasoning: To match Plusle and Minun's buff amount.

428 lopunny
Type Normal/Fighting
Atk 76->101
BST 480->505
Reasoning: Lopunny was fast, but very little else. Now it has a bit of a punch behind that speed.

====587 emolga
====SpA 95->100
====SpD 60->90
====Spe 103->115
====BST 468->515
====Reasoning: To match Plusle and Minun's buff amount.

621 druddigon
HP 77->120
Def 90->110
SpA 60->70
SpD 90->110
Spe 48->55
BST 485->585
Reasoning: See Altaria and Flygon. I made sure to single Druddigon out for buffing because it's Drayden's signature, or one of them at least.
