This is a somewhat upgraded version of Team Aqua's Secret Base from the Double Crisis set.
It will be a nice addition to Cinccino decks by using Boss's Orders that can put some Pokemon into active spot and then stall them.
But there are other ways of utilizing it. For example, Krookodile decks can really make it useful with all their energy acceleration techniques. It's just a great way to make your opponent overcompensate on each active Pokemon in play.
