I'm on day 201. I am very selective about my champions and artifacts. I am making many mistakes. I feed many Legos and Epics to my Rares for upgrading quickly. I know it's wrong to do this, but I am willing to make the sacrifices to make it fun for me to enjoy watching my Champions rank up with new abilities. I have not yet had an opportunity to receive a Lego that I wish to keep and upgrade. I'm currently using 5 Rares with LVL60 and accended 6 starts with two Rares that have awakened 1 star each. All my champions currently have all six 4 & 5-star Life sets. Some artifacts are Legendary, Epic, Uncommon, and common. Happy Raiding!
