Carvanha
Set: Band
@Choice Band
Ability: Speed Boost
EV's: 252 Atk / 252 Spe / 4 HP
Adamant Nature (+Atk, -Sp. Atk)
- Waterfall
- Crunch
- Return/Double-Edge
- Ice Fang
Being banned from LC, one can see why this little guy was feared far and wide by 1st stage Pokemon everywhere. Speed Boost really makes this set viable, along with Choice Band to augment it's fairly good attack (for an NFE.) In order for Carvanha to succeed, however, one needs to ensure that it gets at least one boost from Speed Boost if you don't want it to get revenge killed very easily. Works best as a late game sweeper, taking out its counters before sending it out so that it isn't as easily walled. All of the moves are pretty self explanatory, Waterfall and Crunch being the STAB options, with Return/Double-Edge as a powerful neutral attack. Ice Fang isn't very powerful, but rounds coverage nicely, and to be honest Carvanha doesn't really have many more options other than Zen Headbutt. Other sets are available, namely a Protect set that guarantee's a Speed Boost, but they do not have the power to really be usable.
