Low Kick
Low Kick is a very viable alternative for SD Sceptile, since it hits almost all relevant targets of EQ as hard, if not harder, and it can 2HKO Bronzong. To demonstrate:
+2 252 Atk Sceptile Low Kick (100 BP) vs. 252 HP / 0 Def Bronzong: 170-201 (50.2 - 59.4%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
+2 252 Atk Sceptile Earthquake vs. 160 HP / 0 Def Cobalion: 312-368 (85.9 - 101.3%) -- 31.3% chance to OHKO after Stealth Rock
+2 252 Atk Sceptile Low Kick (120 BP) vs. 160 HP / 0 Def Cobalion: 374-440 (103 - 121.2%) -- guaranteed OHKO
+2 252 Atk Sceptile Earthquake vs. 252 HP / 4 Def Registeel: 272-322 (74.7 - 88.4%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
+2 252 Atk Sceptile Low Kick (120 BP) vs. 252 HP / 4 Def Registeel: 326-384 (89.5 - 105.4%) -- 68.8% chance to OHKO after Stealth Rock
It also does a good 10 extra % to Mega Steelix, which may be quite significant in a game.
The only downside to using Low Kick is for Grass-type resists when you do not want to lock yourself into Outrage, and the declining in popularity Doublade, but gaining the ability to 2HKO Bronzong without support can be a pretty good tradeoff for a lot of teams imo.
