I have a sceptile I was origianlly going to use for competitve battling, but I just nought Soul Silver, and found out that the battle mechanics for physical and special attacks have changed, making my sceptile's moveset pretty useless.... have any ideas on movesets?

Currently:

(note: I have acsess to every game needed)

@miracle seed (big root?)
giga drain
leaf blade (replace it with frenzy plant? Or should I put in some other grass move, or should I just leave giga drain as my one STAB move?
dragon claw (replace it with some other dragon move, or some other type? Surf if sceptile can learn it, maybe?
Aerial Ace (replacement for quick attack, gives me even more type variety and an always hitting move... should I replace it to though?)

Should I also switch out to a different scout pokemon?

Just post your thoughts here. Also, in my team, dark, fire, fighting, and dragon should are types already covered. A lot of the other types depend on how I decide to re work my sceptile

thanks.... I also saw the thing about asking for movesets.....
