Sometimes you can’t be waiting around for your opponent to act. Fortunately, the Organization has more direct methods of taking out its opponents, and they work great in a deck with Metzi and Hydramaskar.
There’s nothing subtle about Acidheart. This powerful exhaust action lets you take down any of your opponent’s heroes—major or minor—no matter what Zone they’re in. You have to wait until round 3 or later, and only a major hero can use it, but that’s fine for Hydramaskar. Have him play Acidheart, and you’re one step closer to using his power!
