It all depends on the player's skill level here... even if Necropolis is chosen, in the hands of a pro, it's unbeatable. In the hands of a newbie, it's weak. That's why... ;)
That's why I say that Necropolis should be ashamed if it doesn't win (meaning the players are newbies).
According to the rules of the current tournament, the pool of available creatures has been reduced (quite significantly), and for Necropolis, only certain heroes have been banned (while leaving one very powerful one).
