Is This a New Card? Is It a Capcanineer?

The card is capacanineer, five in a blue for a four, four artifact creature. It gives itself unblockable and you'd rather use it for crewing. This deck just kind of seemed at odds with what the deck overall is trying to do. I get it with citory, because now you have a pretty big, unblockable artifect creature that you can give lifeling to. And vigilance, indvigil ont's actually might matter on that one, right?
