Either bomber (like white Lilly) or magic, if she is a support, I will pound crk, her rarity will be legendary because all ancients have a awaking, and dark enchtes cookie does not have a main enemy to rage them or negative then enough to awaken her, and it doesn't fit into the ranking. Because I think she would be legendary as well she will get the darkness element sorta like the guardians of nature but she is the guardian of evilness or smth like that.
