Started on the surface; on the first, I expertized the log, took a secondary Castle, horses in the Citadel with 160+ bones. Opponent reveals Gosha in the tavern(, I decide not to go for a treasure but to rush the Necromancer :D. On 122, Griffin Conservatory, level 2 shield +6, have ice on 150 and blind. Klava with 3 pluses reaches the opponent's main in 2 days, where Gosha is holed up behind walls. I check with a scout hero: there are 5 angels, 180 bones, 5 ducks, 2 champions. I run further into the underground to the opponent's Necro secondary. On his turn, Gosha attacks with single griffins, bones, and 8 angels (the rest he sacrificed in max Griffin Conservatory with a scout hero). I have 5 horses, 7 liches, 18 marksmen, 250 bones, 2 angels, 9 vampires, and 11 rags. In terms of battle stats, a slight advantage, but there are 90 mana and oil. In the end, Blindness decides it without a chance.
Thanks for the game!
