Electivire isn't really good anymore. It used to be great back in the days of D/P/Pt, but now its too frail and its Speed and power fall a bit short. Blastoise is fine, but it needs to be in its mega form:
-Blastoise w/Blastoisite
Nature: Modest/Calm
Ability: Mega Launcher
EVs: 248 HP, 252 Sp.Attack, 8 Sp.Defense
Moves: Rapid Spin, Scald/Hydro Pump, Aura Sphere, Dark Pulse/Dragon Pulse
And to add to the long list of Water type resists:
-Vaporeon w/Leftovers or Lum Berry
Nature: Bold
Ability: Water Absorb
EVs: 248 HP, 252 Defense, 8 Sp.Defense
Moves: Scald, Wish, Protect, Toxic/Heal Bell
