Heart Scale after Agate circus

[hav00x]

Well, i'm stuck on charlotte bc my team is horrid against fire mons / double battles. Now i'm doing all that shit about capturing bronzorg, evolving piloswine etc. but i don't have any heart scales to teach piloswine ancient power. Anyone know where i can get a heart scale between agate circus and Ametrine City?

I believe the only way you can get one is by mining. If you save your game in front of a mining rock, you can reset if you don't get a heart scale

I can trade heart scales with you
