Salazzle Salazzle @ Petaya Berry Ability: Corrosion EVs: 4 HP / 252 SpA / 252 Spe Timid Nature IVs: 0 Atk - Substitute - Belch - Flamethrower - Dragon Pulse
Sub to petaya, then belch the night away... (Until that steel type shows up, then you flame)
Salazzle boosts much, much faster with nasty plot, which it learns by level up. For in-game use, the best moveset would be nasty plot, flamethrower, sludge wave, and dragon pulse.
