It would help if you said which Sceptile you are using. I have a Lizard Poison Sceptile deck. I've played around with it and I've found it partners very well with the Skyridge Starmie. Since Sceptile only needs 2 Grass Energy for Solar Beam, you can put in plenty of Water Energy to power up Starmie's Water Gun to its full 50. Core Blast is great against Special Energy decks, especially useful against Metal with its resistance to Grass. The Sandstorm Vaporeon is also useful if you don't want to run as much Water Energy.
