In the first round, he built a Castle and Birds for the last coins. In the second round, he built a Dungeon and an artifact +4 magic power, and a mace for attack. In the third round, he looted Naga's bank, took a green shield, and upgraded to level 2 magic with Bolt and Ice. On turn 141, he breaks the enemy's GO with 100+ Wyvern Monarchs, the opponent leaves the treasure, brings his army, and attacks my secondary town, but I was trying to build Angels there, so there's enough meat. No battle takes place, he surrenders.
Thanks for the game.
