They gave up. In the end, right before the Castle, they upgraded a bunch of roots near the tree, and everyone ran towards the Bolt along the dirt road. Overall, the block slowed down the pace, but by turn 112, the second tree was already revealed, along with 2 Dragon Utopias, 2 Consorts, a fully upgraded Bibla, and two Dweller units behind the zombies. The Taaz visited the stadium and got a couple of upgrades for defense. So, since the Dragon Utopias and Bibla are under the Castle, I planned to take all that around turn 121 and move into the center around turns 122-123, but the opponent couldn't handle the Ifrits on turn 112.

Thanks for the game!
