[Pokemon] Archilles

I decided that because of the fact that I made Metalynx and someone else made Electruxo that was only fair to have one for Archilles. I was thinking this:
Flamethrower
Earthquake
Flame Impact
Will-o-Wisp
252 Speed, 252 Attack?
I'm not very competitive (but I want to be) and so I have literally no idea if that set is any good.

Most offensive sets in competitive battling revolve around specializing in one thing, like only being a physical attacker or special attacker (there are mixed attackers as well, but few pokemon have the stats to pull it off).

Archilles is very average at doing anything in its normal form, so the mega would be recommended.

Looking at its mega stats, it has high special attack and speed, good for a sweeper (something that can take out entire teams, but is often fragile as well). It does learn extremespeed, a solid priority move, ss it would be nice to take advantage of that as well.

A set I came up with(based on the moves it learned in the Uranium Wiki) was...

Archilles @Archillesite
Ability: Rough Skin/Flame Body (Both are solid abilities)
EVs: 4 Atk / 252 SpA / 252 Spe
Hasty Nature
- Earth Power
- Fire Blast
- Extreme Speed
- Ancient Power/Stealth Rock/Will-o-Wisp/Knock Off/(Insert move of your preference here)

The 1st two moves have STAB, Extremespeed has priority, and the last slot... it is what it is.

I would change Fire blast for the one that teachs you the old woman in venesi city.
