Since we're discussing Covert Cloak, has anyone been using it on the ladder? Any thoughts to share? I find it pretty difficult to fit onto teams since its benefits are so limited--outside of the Salt Cure interaction, you get some use against Hatterene (Nuzzle + MF) and get to avoid random flinches and stat drops which come up rarely enough to begin with. With that said, there are two mons where I can see the upside being large enough to warrant using over anything else, particularly if you feel your team is otherwise weak to Garg (and really, what teams don't struggle with Garg these days...)

- The one you're most likely to encounter running Cloak at the moment. Instead of getting walled by Water Garganacl (unless you pack Tbolt I guess) and severely chipped by Salt Cure, you sit in front of it forever and set up with ease. Loss of Air Balloon/Choice item can be unfortunate but there is pretty significant upside if the opponent has Garg.

- Funnily enough, Garg itself can consider Covert Cloak to win the mirror match-up. I think this is particularly applicable for Iron Defense Tera Water Gargs, since one large downside of Tera Water (and a reason I prefer Tera Fairy) is you end up taking 25% from opposing Salt Cures. With Covert Cloak you force opposing Gargs out and set up on them forever. Ultimately I feel the loss of Lefties is a little too tough to stomach, but if you really want to shut down opposing Gargs this could be the tech for you.
There are plenty of other mons where you could think about Covert Cloak--

to name a few but unless you know you'll be facing a Garg it's probably not worth giving up your item slot.
