I got this moveset 4 my sceptile:
Leaf blade (STAB) physical
Rock slide (coverage) takes care of flying, bug, ice.
Earthquake (u know why) takes care of poison fire
The last move is up to you. I either put swords dance to get that extra boost or focus blast because it provides you with coverage against most types that damage you. X scissor is a excellent physical move. You can also have a status move like toxic for example.
Hope this helped;)
