Thank you for the guide! I just started playing in PokeMMO and this looks like a pretty solid guide. I'm interested in doing the fossil farming or the Payday + Covet method once I become stronger. I'm just gonna ask one thing, according to PokeMMO's Covet ability description:
... It will not steal from a wild Pokémon if it faints
So what if you one-hit them with Covet? Wouldn't you be unable to get the item if you maxed Attack? Thanks!

About the Fossil Farming one, I just realized that some may be Sturdy so the Covet will work. Although, I still don't quite get about the Coveting the Heart Scales with max Attack.
