On the first month, I took over the opponent's Inferno town and settled in with Efreeti + Pit Fiends, built 3 Griffin Conservatories for 4 Angels, a level 3 Dragon Fly Hive. On month 1 day 31, I broke 3 Dragon Utopias, which gave Knowledge, Attack, and Magic parameters with a Cuirass, spell power went up to nearly 30. I also flagged 2 external Devil dwellings in two super-treasures. In the Grail building with Town Portal, I got Town Portal + Dimension Door. Also had Kyrre level 17 paired with Gunnar and control, so things should have gone fairly easily even without speed artifacts. On month 1 day 35, I recruited Arch Devils and portal'd them, took over Pink's Rampart. Behind the mountains, the opponent was visible, decided to check there and jumped in with Efreeti and Armageddon for 2k damage. Marusya immediately bounced with 2 Angels, resulting in a surrender.
Thanks for the game!
