I collected 2 Dragon Fly Hives with 8 Wyverns each on week 1, got Griffin Conservatory 3 on day 122, then exited, took the center, some scuffling with low-tier troops, eventually drove off the opponent, built Town Portal and Dimension Door, took 2 Dragon Utopias. The Executioner, after jumping into a one-way portal, found nothing special there and surrendered.
Thanks for the game.
