What this means if you are building it
You can own 113 of the 118 priced cards in Steam Siege for about $180. The median card is $0.27. The remaining $252 sits in just 5 chase cards, and one of them (Gardevoir EX (Secret), $99) is 23% of the entire set on its own. A full set is not one long climb. It is a cheap, fast 40% and then a very short, very expensive tail.
