For anyone wondering, the odds of flinching after 5 hits with King's Rock/Razor Fang are about 41%.
The odds of flinching from Serene Grace Air Slash is 60%.

[@wisteria] If I may request for future reference, (I don't need to get it now or anything) I think it would be cuter to give Minccino a King's Rock to wear as a crown rather than having it carry a Razor Fang around, which it would probably just hide within its fur. I imagine a King's Rock would fit pretty snugly around one of Cinccino's huge ears.

By the way, how much would an ability capsule cost?

It's tempting to spam them a bit later on, if possible, so Shuckle can switch on and off of Contrary Shell Smash, since Contrary is incompatible with my favorite Shuckle set.
