I was planning out a team I might use later on, and I realized that if by any chance I could get rid of slakings ability, he would be awesome. So maybe theres a mpve, item, or ability that I could use to make slaking perfect
Mummy - Changes whatever hits it to the ability Mummy
I think that's it.
It may be possible to have a Pokemon on your team use gastro acid on slaking but that might be only in double battles so in single battles there would be no way of getting rid of that ability
