I don't care what anyone says; this card is a champion. To start, it's free. FREE. Who doesn't like free things? Second, it flies. That means it can block almost every kind of creature. Thirdly, it's an artifact. Anyone like metalcraft? Sure, it can't do damage on its own, but it's there to either be a blocker, add to your storm count, or get you metalcraft quickly and it does all three quite well. Put some Shuko or a Bone Saw on this card and you've got a 1/2 flier for 1. There aren't many flying creatures for 1 that are much better than that.
Pros: Free, great blocker
Cons: Can't attack without support
