Of course not. You'll need to have it trigger independently or employ something like Skill Swap to isolate whether the pokemon has an HA.Does it tell you if a Pokemon that arrives for help has an HA?
This worked relatively easily with Skarmory because two of its three abilities - including its HA - responded to attacks. So you could tell relatively quickly whether it had Sturdy, Keen Eye or Weak Armor.
But a lot of other HAs won't be as intuitive as Weak Armor was. And if it's true that Mareanie won't call for help itself and you can't chain it after it snipes Corsola, I'm thinking it's going to be impossible to legitimately find one with Regenerator. Merciless will be the way to go.
Nabbing a Prankster Sableye pre-Bank may prove problematic for the same reasons.
