I thought I didn't have much chance, seeing my opponent had higher level cards than mine. Luckily it was a Melee Mayhem battle and I knew the Exploding Dwarf and Hobgoblin were good for that. Had to take a risk on Lord Arianthus and it paid off. I wish I could be as good with tactics all the time, or maybe I just got lucky :)
