Started on the surface, explored the first log, took a second-tier Castle, and had 160+ skeletons in the Citadel. My opponent was using Haven and had a powerful Knight in the tavern. I decided not to go for the treasure and instead rush with Necropolis units. On turn 122, I had 2 Shieldbearers with +6, an Ice Golem with 150 attack, and a Blind. My Knight with 3 upgrades reached the opponent's main castle, where he was defended by a Knight, 5 Angels (180 skeletons), 5 Ducks, and 2 Champions. I continued into the Dungeon towards the Necropolis. On his turn, the opponent attacked with Griffins, Skeletons, and 8 Angels (he had scouted and maxed out his Skeleton production). I had 5 Knights, 7 Liches, 18 Marksmen, 250 Skeletons, 2 Angels, and 11 Wraiths. I had a slight advantage in terms of stats, but he had 90 mana and Oil of Speed. In the end, Blind proved decisive, and I won without much difficulty.
Thanks for the game!
