The Giant Skeleton can be used on attack and defense. The Inferno Tower and the Hog Rider are used to to chip away and cycle, building up defenses. How do you open? It depends on your opening hand. If you have Giant Skeleton, Baby Dragon, and The Log go for the opening push. If you have a Hog Rider and an Inferno Tower put the Inferno Tower first, then use the Hog Rider. If you have neither, cycle, since this deck can cycle pretty well, too. The Baby Dragon is interchangeable with the Wizard, and The Log is interchangeable with Zap. I made this deck myself, and it dominates Arena 4-6. This deck is good for grinding quickly. Enjoy the versatility of this awesome deck!
P.S This deck can handle fairly low level cards. And this deck has the Barbarian Barrel in place of Fire Spirits
