Since you liek Scyther, I'd go for a Bugsy Run. Gym leader runs are all the rage. This run leaves you with:
Scyther, Kakuna, Metapod
Brock (anime) run is something I recommend to everybody. Using Sinnoh only, you have:
Bonsly, Hapinny, Croagunk
Or you can go old-school with:
Onix, Geoducde, Zubat
Monotype runs are also worth your time. How about mono-Grass?:
Something Like: Torterra, Wormadam (Grass), Cherrim, Tangrowth, Tropius, Roserade
Baby runs are fun. I recommend:
Togepi, Mantyke, Elekid, Happiny, Bonsly, Chingling
Oh, and NU-Runs are cool. Something like...:
Beautifly/Dustox, Chimecho, Pachirisu, Chatot, Skunktank, Octillery
