I see the gowen one in use and have seen the falkow one as well. Not sure 2000 gran is worth it for the cards you are getting though. In my opinion the best one of the 4 ( in terms of cards) is the refess pack.
I bought several cards from the phidience sphere- did not get Dilate. I like the victory chic alot. Best way to handle these guys is to use some from of " corruption" on them. I just haven't found in my cards that type of grim.
Nought's had, all's spent, Where our desire is got without content;'Tis safer to be that which we destroy Than by destruction dwell in doubtful joy.
