-10k starting: 9100 for the castle and 900 for the color.
On the first day, I had a 4-hero lead on the Kentaur units + a stable. On the second day, I bought 8 more heroes, and saw a couple of Imps (200 and 300). I played as Necropolis, farmed gold, and built a Guildhall. On the fourth day, I took the Swamp and placed Ducks. I found 4 Hives with 3 Ducks each + upgrade = 122 experience through 3 Crystal Mines with 250+ Skeletons and 33 Ducks. I spent a couple of days in the center: a chest with 20 Medusas, Sandals +2 All, a Bible, and a Hive +8. On day 125, I took a chest for 13 Silvers with all magic, but my opponent surrendered. He had a double Grand Order with Devils and Fairies.
Thanks for the game!
