Thank you the both of you. I was hoping to keep the strongest ones, such as Canon, Dhimitrios, Oberung and Diamond, and ones I like a lot such as Molnyia and Lyyli. I still only have one 6* and a few 5*, so having some good 4* around can be helpful :)The problem is that I heard that fast units, such as Angela and Yuriya are also great, with good DPS.
