Yeah, but you can give it this set:
Yanmega@Wise Glasses/Wide Lens
Modest
Trait: Speed Boost
-Protect
-Bug Buzz
-AncientPower
-Hypnosis/Giga Drain/Air Slash
Protect first turn, like everyone says, then sweep. Last slot is your choice. Hypnosis for sleeping, GD for recovery and Rock types, Air Slash for a 2nd STAB move.
Or this set:
Yanmega@Choice Specs/Wise Glasses
Timid
Trait: Tinted Lens
-Air Slash
-Bug Buzz
-AncientPower
-Giga Drain/Hypnosis(Only without Choice Specs)
Tinted Lens negates the loss in power of a move if not very effective. So a Choice Specs set is ideal since the opponent can't shut you down with as many resistances. Use Hypnosis instead of GD only if Choice Specs isn't for you.
