I don't know about anyone else, but I found the "sits there looking dumb" part to be kinda funny.
I've never thought about using him seriously in my deck, but that's probably because I only have one copy of him. Building your deck around him just doesn't seem feasible for Gowen-they're all about their level 2s and 3s rocking the house from day one. Refess can pull that Dragonrider strategy off more easily becuse they're about DF-which Gowen is not. Plus, Refess generates SP better than Gowen.
