Reverse 1999 Lucy build guide: Best teams

Timekeepers can use Lucy as a DPS character for their Reverse 1999 teams. She excellently syncs with Arcanists who can deal Reality damage and gains either Moxie or Eureka. Additionally, she fits well in most teams due to the Afflatus advantage she gains from her Ultimate.

Timekeepers can pair her with 37 of Star Afflatus, Marcus of Plant Afflatus, or Isolde of Spirit Afflatus for Support. 8 of Intelligence Afflatus and Getian of Beast Afflatus are the best alternatives for Support or while playing Mane’s Bulletin. The character also works excellently with Bkornblume of Plant Afflatus as a Support.

Timekeepers can use the Tooth Fairy of Star Afflatus, or Vila of Plant Afflatus as a healer. Yenisei of Star Afflatus is the best alternative for the healer slot.
