Just recently finished the main storyline in my Omega Ruby Wonderlocke. The final team looked like this:
Electrode Level 60. Soundproof Electro Ball, Light Screen, Discharge, Hyper Beam.
(Mega) Pidgeot Level 64. Tangled Feet/No Guard Air Slash, Hidden Power (Psychic), Mirror Move, Hyper Beam.
Glaceon Level 60. Snow Cloak Ice Beam, Shadow Ball, Barrier, Hidden Power (Ground).
Steelix (aka: Thumper) Level 61. Rock Head Earthquake, Rock Slide, Strength, Gyro Ball.
Cacturne Level 62. Sand Veil Needle Arm, Spiky Shield, Power-Up Punch, Feint Attack.
Dustox Level 61, Shield Dust Bug Buzz, Psychic, Sludge Bomb, Quiver Dance.
Frankly I was surprised Dustox made it. He was like the fifth pokemon I got and somehow he just managed to stay on the team from then on. I nearly lost both him and Cacturne to the Elite Four while everyone nearly died in the battle against Stephen (Electrode and Glaceon especially!)
Pidgeot managed to be the star of the team. Whoever sent it obviously caught it on the first route in X or Y because it was only level Three when I got it in Lavaridge Town. Fortunately I had already played though Alpha Sapphire and knew where to find the Pidgeotite. I never quite got around to teaching him Hurricane like all Mega Pidgeot should know, but for playing through the game Air Slash was more than adequate. Also, blasting things with a powered up, STAB Hyper Beam is oddly satisfying, especially as it uses its Gen 1 sound effect. Maxie's Crobat never knew what hit it!
Sadly no Locke is ever without its deaths and I had quite a few. Tentacruel, Zangoose and Charizard were all with me for a long time and by rights each should have made it to the league were it not for a couple of stupid mistakes. Persian, Forretress, Azumarill, Flareon, Pikachu, Combusken, Chinchou, Marill, Tentacool and Whismur also fell during the challenge, but no death hit harder than Blue the Deino I was so determined to use that little bugger after Persian died, but that stupid Sandslash got in a critical hit!
Oh well, time to do the Delta Episode, though I'm not sure if I'll keep the locke format going now that the main storyline is over.
