But old Necropolis could summon Undead host, Vampire countess, Eternal guardian and Banshee at the same time. What chances does new one have to do the same?
At this moment Necropolis is much like Revolt - maybe its cardset is a bit stronger due to Undead keyword concept, but its rarity and cost are higher, and resource gain is lower. And ability to summon Necropolist with Necromancy, Crypt, Lich or Necromancer doesn't worth random Undead cardset.
