I use him. Is a good conference against Leotaur with only lvl 4 Monsters on your field. Oh and Gearfried has the down not could be strengthened by own equipment and not used for cards which need normal monsters like community Charity
LOL! I just tried to farm him (Cerberus). Anytime he summoned Gearfried the Iron Knight, it showed the card as 0 ATK/0 DEF without name on it. I had my Eatgaboon Set for his last Timewizard. Last Turn, Cerberus at 9k ATK, he flip summons his glitched Gearfried, then normaled his Time Wizard and I didn't get the chance to activate my Gaboon, nor did it do the "effect activating"-bling (don#t know how to describe, you know what I mean) but there was just the coin (in the same second it summoned). Pure luck it wasn't heads.
