We started from scratch. There are two hidden spots for fighters, and I used them to build up my forces. In the beginning of the first week, I found a stash of 50 creatures, which was very helpful, including when taking the hidden spots for fighters. I wanted to reach level 122, but without angels, it felt risky to attack the green dragons, so I decided to stay for one more day to gather angels from two consecutive battles. However, my opponent couldn't handle his own Guardian Angels.
Thanks for the game.
