I'm planning on using Mega Salamence. I've already decided it's going to be physical-based, but I'm not sure if I should run mixed or not. Here are my two potential sets:
Pure Physical
Salamence @ Salamencite
Ability: Intimidate -> Aerilate
Jolly Nature
EVs: 252 Atk / 252 Spe / 4 HP
-Dragon Dance
-Double-Edge
-Dragon Rush
-Earthquake
Physically Biased MixMence
Salamence @ Salamencite
Ability: Intimidate -> Aerilate
Naive Nature
EVs: 252 Atk / 252 Spe / 4 SpA
-Double-Edge
-Earthquake
-Dragon Dance
-Fire Blast
Which one should I run, and why?
