He started playing aggressively because of Malekith and Dungeon. His opponent had a Necromancer hero, a Necropolis town, and a Necropolis castle, so it was difficult to counter with my setup. Thanks for the game!
It's funny, but you had 2 Necromancers from the first week, Sandro and Klava, hidden Archons, and a Rukh behind the Dungeon, but Malekith is overpowered; he couldn't win against my "chocolate" (presumably a strong strategy or hero).
