Well, after nine days and over 100 matches, I FINALLY managed to complete the Win 5 in Survivor
mission. Believe it or not, I managed to pull it off using a GHEIST
deck in Survivor ELO
I still think that the mission might be a bit too difficult (especially for newer players who don't have a large pool of cards from which to draw). Maybe instead of such a difficult mission, do a two-fer... Say, one mission in which you have to win two or three in a row, and a second where you have to win 25 (or 30... heck, I'll even accept 50) matches in Survivor? That way it would be accessable to newbies who are still building their collections, it would force those with large collections to actually commit the time to complete the mission, and would reduct the level of frustration all ways around.
Oh, and Rapture-b... the mission is "Win five Survivor
matches in a row," not win fifteen times.
