Alright... my Input would be...
Electivire: Ditch fire punch for EQ
Jirachi: Perfect. But Charizard would be a detriment to the Water pulse.
Pory-2: I would say... Remove Thunderbolt for Toxic, but otherwise great.
Charizard: Perfect, but Mixed Belly Drum Charizard Y can do the same thing... With more surprise... but still good set.
Scizor: I would Suggest AV, maybe go...
Scizor@Assault Vest
Adamant Nature, Technician
252 HP, 252 Attk, 4 Sdef
-Bullet punch
-U-Turn
-Bug bite/Aerial Ace
-Knock-off (Transfer, but still 2 gud)/Pursuit
Pursuit applies some extra pressure while both Bug Bite and Aerial ace are good, U-Turn and Bullet punch are musts... You should see it, this thing has taken a STAB Fire type attack (Albeit from a Lampent) but still impressive, and lived long enough to kill w/ Pursuit.
Slowking<Slowbro.
Slowbro@Rocky helmet
Bold Nature, Ability: Regenerator
252 HP, 240 Def, 16 SpA
-Calm mind
-Scald
-Flamethrower
-Slack off
More defensive at it's base, and knockoff+Fake out users with sash are screwed up by the Rocky helmet, Burns are okay on Slowbro, but Toxics will kill, so Lum/Pecha berry is also usable.
