Why adding fury swipes and double slap when there is fury attack?
Why does swagger and flatter raises the foe's stats? Dous it make them "hurt themselves in their confusion" with more power?
3. Adding detect when you have protect?
WOW a status effect move with 100 acc. No fair!
No. 1: For Variety.
No.2: Yes, yes it does.
No.4: C'mon, why wouldn't you want a 100 acc sleep inducing move? At least only a few Pokemon can learn it. Also, it doesn't effect Grass Types.
Hope I helped!
