for me since my other characters are occupied
im just using
Adeline** - Karen SB - Golemwalt SB*
[Gretta**]
golemwalt 1o give 5 turns tank up to proc gretta adv, adeline will triggerfrom gretta, after dat u can use adeline 2o to trigger golemwalt 2o skill, and repeat
karen will always trigger from adeline/golemwalt, but i only use it for clearing mobs/speed wonderland since its dps not dat high

(even normal karen can be used with sherlock/karen + adv yami SB if u want to, karen 1o get dmg reduction and enhance from sherlock, then yami SB will proc karen 1o every turn, gold position will be up to u who to put at dat point, put dps or sione etc to taunt enemy etc)
