Agreeing with Luiii. As I am playing cKadilen since some months and I have Eve and Lianna, here is my opinion specifically to your green hero roster:
On attack, I found her behind the Eve-Lianna pair which you actually have. She is too random, but still better then most S1 heroes. I like to play with 2 heroes of a color, so I have no use for her on attack except AW. If you played 3 or more green heroes a lot, then she would have a place for sure.
On defense, she would be your best tank of green heroes and she is really good there helping me in 5* tournaments without red heroes, though I have generally less problems attacking her, as Eve-Lianna have a good chance to dispel and snipe one of three opponents. But she forces me to take Eve…
I would never give her emblems from cCaedmon who is a must hero for me in all 4* tournaments. He can dispel or heal status as needed, is fast, snipes quite well. In fact, I gave first emblems to Melia and Belith who I need in more tournaments and events than cKadilen. But emblems are up to your priority.
Ask yourself if you need a fast status cleaner on attack or a very good green defender and when you have emblems for them.
