A Dragon Dance set for Gen 8 NU if you want to use one. Dragon Dance Aerodactyl got a bit better with Bronzong gone from NU, as you would have to slot in Crunch for Levitate Bronzong. Now, you don't have to use Crunch on Dragon Dance Aerodactyl. Dragon Dance allows you to boost your Attack and Speed stats, and it shouldn't be too hard to find a setup opportunity. Stone Edge is for a powerful rock STAB. Earthquake provides coverage against Steel- and Poison-types like Copperajah, Dragalge, Salazzle, Toxicroak, Duraludon, and the rare Silvally-Steel. Aqua Tail is for coverage against ground types like Silvally-Ground, Rhydon and Mudsdale. Aqua Tail is especially useful for Mudsdale, as the move allows you to 2HKO Mudsdale after Mudsdale, as shown in this calc:
+1 252 Atk Life Orb Aerodactyl Aqua Tail vs. 252 HP / 252+ Def Mudsdale: 237-281 (58.6 - 69.5%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
Possible damage amounts: (237, 239, 242, 247, 250, 252, 255, 257, 260, 263, 265, 268, 270, 273, 276, 281)
For those wondering, "Won't Mudsdale's Stamina stop the 2HKO?" Here is a calc for a +1 Life Orb Aqua Tail that did minimum damage to Mudsdale:
+1 252 Atk Life Orb Aerodactyl Aqua Tail vs. +1 252 HP / 252+ Def Mudsdale: 161-190 (39.8 - 47%) -- guaranteed OHKO after Stealth Rock
Possible damage amounts: (161, 161, 164, 166, 166, 169, 172, 174, 174, 177, 179, 182, 182, 185, 187, 190)
Do keep in mind that was for mininum damage, so Aqua Tail 2HKOes Mudsdale, which is pretty nice.
Enjoy!
