On the first week, I took a native secondary hero and uncovered the shroud, revealing the opponent's respawn. On the second week, I gathered an army and attacked the hero in the castle, but was defeated and bought myself off; amigo's army had only one angel left. On the 3rd week, I gathered all the cannon fodder and attacked again, this time using a mage to blindly snipe the angel with a shot for 133.
Thanks for the game.
