Ability: Wonder Guard
EVs: 252 ATK, 252 SPE, 4 ANYTHING (It doesn't matter)
Nature: Lonely (+ATK, -DEF), Adamant (+ATK, -SP.ATK), Naughty (+ATK, -SP.DEF)
Characteristic: Likes to thrash about (+ATK, 31 IVs)
Moveset:
- Swords Dance
- X-Scissor
- Shadow Sneak
- Aerial Ace/Night Slash/Metal Claw
Battle Strategy:
- Use X-Scissor or Aerial Ace/Night Slash/Metal Claw or Shadow Sneak depending on the damage it will deal to your opponent.
- Repeat step 1 but when you lose your focus sash, use Shadow Sneak.
Swords Dance is there if you think your opponent isn't going to damage you like setting-up hazards, using a move that will not K.O. you or switching etc.
Aerial Ace/Night Slash/Metal Claw is there for type coverage in case an opponent is resistant to your STAB X-Scissor.
This strategy does well unless you have a status problem, like a burn; there is hail or a sandstorm raging; an opponent is resistant to your attacks; an opponent has a high defence; you are tricked etc. a choice item (but then they waste a turn) or Chesnaught uses the move Spiky Shield.
