Attack with your hero, use Galway Steamwhistle's ability to ready your hero. Next pay two resources to strike with the Sword of Zeal. By striking with the Sword of Zeal the Hauberk of Desolation allows you to ready Galway Steamwhistle, and because you deal two damage with the Sword of Zeal, you are able to ready the two resources that you expended in striking with it. Repeat as many times as desired to do infinite damage.
