While Vanilluxe isn't my favorite, I do have one trained - but it's completely different from your build:
"Flava Flav" Vanilluxe@Occa Berry (or Salac or Apicot depending on which type I want for Natural Gift) 248 HP, 252 Atk, 8 SpD Adamant Ice Shard Avalanche Natural Gift (80 Fire or 100 Fighting or 100 Ground) Explosion
Also Frost Breath is only effectively 90BP because crit damage is lower in 6th gen. It's like an Ice Beam that can miss, but does full damage against CM users I guess?
