Gee, i would really HATE anyone to think the challenge response deck is anything but AWFUL - mindless card-cycling, any monkey could do it. John's and Dave's ideas are for proper decks - this isn't a deck IMO, it's an abuse of the existing cards. How about the following even more awful deck to reinforce the point: 5 Uriah Winter 5 March Halcyon 5 Giuliano Vincenzi 5 Rufina Soledad 8 Parthenon 2 Info Highway 20 Fortitude Master Discipline cards 6 Freak Drive 6 Soul Gem of Etrius 16 Force of Will 16 Daring the Dawn [or 12 plus 4 Day Operation] 8 Tasha Morgan 8 JS Simmons 13-14 different cards, totally mindless automatic "strategy" ... to me this is what is meant by regressive-degenerate. It's not unbeatable, thank Caine, but just think how TEDIOUS this would be for a wide range of decks.
