Even though It looks more like a aggro deck, you're more often killing your opponent by trading with Leper Gnome and Kobold Sandtrooper.

The deck also has Plated Beetle as a source of "healing", Volatile Elemental to help with the board control, Mecharoo to have a extra 1 drop that is a bit more hard to remove in this brawl and Roll The Bones that basically draw your entire deck (this way you'll never get out of fuel).
