More than anything I just want its ATK and SpATK stats swapped.
But if I got to rely solely on movepool, then just match whatever physical moves its got with special moves of the same type.
>Can learn Rock Slide, so give it Power Gem
If Persian and Vespiquen can for some reason, so can Sceptile. Plus plenty of Grass types can via Nature Power.
>Can learn Brick Break, so give it Vacuum Wave
Aura Sphere could be a good alternative, but some priority would be beneficial.
>Can learn Earthquake, so give it Earth Power
If Venusaur and Rillaboom can, surely Sceptile can too.
>Can learn Night Slash, so give it Dark Pulse
All sorts of Pokemon can learn it, so no big deal here.
>Can learn Thunderpunch, so give it Thunderbolt
Probably a stretch, but fits thematically with Mega Sceptile having Lightning Rod. Discharge could work, too.
>Can learn X Scissor, so give it Pollen Puff
Plenty of Grass types can learn it, plus Sceptile looks like it has puffs of pollen on its back anyway.
