>>25123630The ability is fine, it lets it counter Thunderus, provided he didn't predict the switch and use HP, which some people don't even run anyway.
Sceptile could benefit a lot from a better movepool. Earth Power would probably be the best, since it would let you shit on Steel and fire types the most, as well as the odd Poison type used to check it, like Nidoqueen.
Close Combat could let it wallbreak and 2HKO Blissey with a little bit of attack investment, or if you have any hazards up at all. Blisey is one of Sceptile's main counters anyway. It could also be pretty good on the Swords Dance set even though Sceptile already learns Drain Punch.
Thunderbolt would be nice too. It seems odd for Sceptile to have Lightning Rod, but can't learn any Electric attacks. Either way, it could rape any Flying Type slower than it and make it a major pain to switch in on if you predict a switch to a Flying type, which normally counter Sceptile too.
