Adding all those stat boosts is going to leave it at a 660 stat total... The mark we're supposed to be going for is 600. I'll boost the attack to 130 though. I'm also trying to keep the flavor relatively sound so shell smash leaf blade and tail glow are out. But i'll add the rest. ALSO:Increase the attack to 130, increase both defenses to 120, increase special attack to 110, and give it Power-up Punch, Shell Smash, Tail Glow, Hurricane, Brave Bird, Leaf Blade, Extremespeed, Earthquake, Shell Smash, Stored Power, and Sucker Punch and I think you'll be close enough.

Volt Absorb + Electrify + 150 Speed + 120 Attack + Power-Up Punch + Priority Moves = A serious mindgame in which none of the opponents attacks do anything but restore Pachi's HP and Pachi racks up attack with power up punch before obliterating with shadow sneak and extremespeed.
