2* Maxxed Layla. Because she was my first max emblems, and is probably the most loved 2 in the game.
3s: Aim is keep one maxed copy of all including costumes. Got around 46 or so unique maxed heroes and about 4-5 left to complete. The 3s I don’t have are Pixie and Bauchan.
I have a few random extra unlevelled event or S3 heroes that I haven’t decided to keep or feed. I’ve kept an extra Frosty because he’s the only 3s blue healer.
Some I just like to randomly play around with. Like I did with Rudolph. I’ve pulled so many of him I decided to make a full 5-member sleigh team … just because I can. So I have 3 maxed Rudolphs and 2 waiting for whenever I want a break from levelling 4s and 5s. Fed away the rest, some to Rudolph himself (Better to laugh at the game than lament on the lack of pulling anything over 3 lately!!)
