 Pro Tip!
Steam-Kin rewards you for playing cheap red spells -- which you were probably going to do already! It's most commonly used in conjuntion with Experimental Frenzy to create a near-limitless wave of spells and mana off the top of your deck. Add a second Steam-Kin to the board and watch the chaos unfold.
