Rotation:
Layla E
Furina E - Q
Layla Q
Miss Faruzan Q - E
Xianyun Q - EEE - POGO SPAM
Real rotation should be refreshing Layla E before Pogo Spam to get a little bit of sustain due to Xianyun's very low HP and resistance to interruption.
Not the best team build for this as I lack of Noblesse here. Should work better with Shenhe instead of Layla because she has access to that but when I tried with Shenhe I died a little too much for my liking. Skill issue. Also Furina is in Golden Troupe because Layla is already in Tenacity but with Shenhe Noblesse, Furina could be in Tenacity for ATK% support Xianyun instead of personal damage. Also mind that not all characters have a full build here. Layla is not on all lvl20 artifacts at all. Miss Faruzan is obviously in Emblem. Layla and Miss Faruzan are C6.
