Sweeper Defensive Set:
Scyther @ Eviolite
Ability: Technician
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Swords Dance
- Bug Bite
- Aerial Ace
- Night Slash / Knock Off
Moves:
Swords Dance (eviolite should make you able to hung on at least a single move, and then you can sweep your opponents with technician STAB aerial ace)
Bug Bite (60 base power, this means technician. with STAB, it has the same power then aerial ace, and can even eat the target's berry. this is not very useful in generally, but with technician it becomes AWESOME)
Aerial Ace (duh. is the best move for a sweeper technician scyther, and after a swords dance, which turn you should survive due to eviolite, you will completely break your opponents)
Night Slash/Knock Off (night slash for wall breaks, and knock off for removing items. but I would still go with night slash becuase it deals more damage, and with the critical hit it will completely "tear" ((lol this is literally what a "slash" move does :3)) the target
i've been swept by this 3 times and can say, it's PRETTY MUCH useful
