An interesting map by Xiedu http://www.maps4heroes.com/forum/opinions.php?map_id=784&game=3
People say it's impossible. I glanced at it yesterday and was seriously puzzled after the first turn of the AI (it wiped out 2,000 Ghost Dragons with Armageddon in one go; I thought it was a bug, but it turns out that's how it's designed). I haven't looked any further yet.
There's a catch: the map was made by Chinese developers, so all the names and messages are unreadable. But, I hope that for true connoisseurs, this won't be a problem.
