I just today purchased the weekly special 600 crystal pack and was very happy with my pull of new cards. Got something like 6 NEW rares, including Sifter Wurm, Overcome, and Obelisk Spider. I could see Overcome making it in to a lot of green decks as a finisher. Now I want Planeswalker Samut to be released so I can build some kind of R/G ramp exert deck.
