what are annoyer in competitive battles just want to know so I can try to finish my team
Here's a list some of them:
Sableye (M) @ Focus Sash
EVs: 252 HP / 128 Def / 128 SDef
Calm Nature (+SDef, -Atk)
Basically here you would poison or burn your target (depending on type). You will survive 100% with focus sash. Then, keep on using protect and recover over until your opponent faints.
