I've actually never used Sceptile...actually the only grass pokemon I ever used successfully was Tropius...the thing is, grass is rarely ever paired with anything other than poison, and when they're paired with other things, they usually loose most of their grass attacks, and some don't even learn any good grass attacks...Tropius was able to learn Fly, making him halfway useful...I also really liked magical leaf, that was a great new attack...I just hope the 4th gen has some good grass types ._.;;
Oh, and cute avatar Kairi ^^;; Sakura, right?
