I was happy to get 3 more old Phoenix artifacts from the current event and max out my Fire Phoenix to level 10. I used the MA recipe twice, however I was also able to successfully finish the entire event so I got the 3 old Phoenix artifact for rewards as well.
Please can we have more events for other artifacts so that other evolving buildings (such as Bears, Stonehedge, Gingerbread House, Valentines....) have the same chance to max out? This makes the game fun and makes me happy.
