Re: Challenge: That's Not My Deck
This one's tough. The basic idea is that a bunch of the cards in your deck are randomly changed for other cards in your deck. Thus, control and combo decks are pretty much out. I think the changes it makes are the same for the rest of that gauntlet, but I'm not sure.
Your opening hand will also be randomly changed, *except* for the lands, which seem to remain the same every time, though occasionally I get either Eye of Ugin or Eldrazi Temple in my hand, which I don't think were in the decks. I was using some of my 499 card decks, hoping that the 5-colours would mean that the randomness would affect me less, as I could still cast cards. While it is true I could still cast most cards, the average card is quite a bit weaker, and the inherent instability of such a large deck meant I didn't get past about round 4 or 5 with them. I haven't tried with any smaller decks, yet.
The AI decks are either randomized as well, and/or chosen from your playlist, rather than the standard challenge mode list. I haven't found any pattern yet to the randomization yet.
