Full Offense, ResTalk, or Other for this Mega Gyarados?

I’m currently raising a Gyarados for competititve use in Omega Ruby. But I am at a loss as to what moveset to put on him. Even after searching Smogon and Serebii, I still have no idea what to do. His build so far is:

Gyarados@ GyaradositeTrait: Intimidate –> Mold BreakerNature: AdamantEVs: 252 Atk/188 SDef/20 Def/48 HP- Waterfall- Crunch- Rest/Stone Edge/Earthquake/Roar- Sleep Talk/Dragon Dance/Thunder Wave

My initial idea was a bulky ResTalk set with Crunch and Waterfall for dual STABs. But then I thought of pairing his stellar Attack and modest uninvested Speed with DDance, and either EQuake or Stone Edge for coverage. But then my mind wandered to a more support/phazer role with Waterfall, Crunch, Thunder Wave, and either Roar or Dragon Tail. I also considered removing the Gyaradosite and giving it Leftovers. In other words, I’m terribly confused and I’m hoping someone can give me a nudge in the right direction.

Hmmm…

This is completely personal preference, but I never really liked ResTalk. I find it too unreliable and unpredictable to use, and one time I lost a game due to Sleep Talk selecting Rest both sleep turns. I also think phasing should be left to stuff with better defenses- although it does have great bulk, its high Attack just screams “SWEEPER!” for me. Here’s the set I would use:

Gyarados @ GyaradositeAbility: Intimidate -> Mold BreakerJolly NatureEVs: 252 Atk / 252 Spe / 4 HP-Substitute-Dragon Dance-Waterfall-Crunch / Earthquake

The last moveslot is up to you: more STAB, or coverage? I would go with Earthquake, to be honest, to smack around stuff like non Air Balloon Excadrill and Rotom-Wash.

Hope I helped!
