Being revealed as one of the Kaladesh Inventions means that more copies entered the market. Inititally, pre-ordering for $50 on Star City Games, some players feel that this is too high of a price for it. Being such a rarity, however, with such beautiful artwork, this should be a valuable card down the road. In particular, players of Kemba, Kha Regent and Zurgo Helmsmasher, both popular Commanders who frequently include this card, may want this Invention to pimp out their decks. Really, any Commander deck that attacks with their Commander on a regular basis can use this Equipment. The $50 price tag seems more than fair for the relative rarity of this card and its usefulness in Commander.
