This would be more like it:
Dragon Claw
Leaf Blade
Hidden Power/Toxic
Crunch
Attach a Petaya berry to him, too.
i'd put leech seed over dragon pulse. leech sub is enough to make whoever resist energyball+focus blast to make the switch, allowing you to hit whoever switches in HARD. with sceptile's sp.att, energy ball and focus blast are going to put a dent on pokemon who are resistant anyway. unless you have a big dragon problem, i don't see why you need dragon pulse.
Idk much about Sceptile, but I was thinking this might work..?
Leech Seed
Protect
Detect
Dragon Pulse / Energy Ball
I really hate Focus Blast for its 70% accuracy. =\
Sceptile can basically Leech Seed the opponent and Protect & Detect to slowly kill or just force a switch. Dragon Pulse is mainly for the surprise factor, and Energy Ball is standard.
I have no battle experience, so I'm not so sure about this.
That was the standard for the 3rd generation. Since those were special attacks. Now they are physical attacks. Which won't be good for this Sceptile.
Sceptile@Petaya Berry
Modest
-Energy Ball
-Substitute
-Dragon Pulse
-Focus Blast
Like okka said. It's a standard set now. Grass Knot is always an good attack to use also.
I'd suggest Leaf Storm over Energy Ball.
