"Two Seasons: Winter-Spring 2017". Online games for rating (reports, discussions).

A decent start. I can see 3 Crypts, 2 Dragon Fly Hives, Stables. Air elementals are built, Labetha is recruited, and the 6th hero is also Crag Hack. All the Crypts turned out to be large. There was an external Marketplace in the adjacent zone, so on the first day I was able to set up Birds in the Citadel. Both Labetha and Crag Hack leveled up perfectly. The second week started with a fail – I forgot to buy the spell book for Crag Hack. So he went into the Treasury without it, and at the start of the third week he even took Dragon Utopias without a book (9 Birds and ~30 Duck Wyverns handled it perfectly well). I got stats and the Helm. A couple of days later I got Town Portal from the Grave Mausoleum, took a couple more Dragon Utopias and a couple of Libraries, collected a bunch of Dragon Fly Hives (and there were still plenty left). On day 142, with Labetha, I took the opponent's main town and he surrendered. Thanks for the game.
The main hero was Crag Hack, of course (I made a mistake in the header), although Labetha was also perfectly suited for that role.
