Lynx / Heroic Gilgamesh / Celestia / Hyper Alch / Sulis - this would likely be the best combo if you make Gilgamesh your main attacker, even if its only for tap damage.

She's a GUR with a dmg skill so she's a good choice - she also benefits from Celestia's buff. You don't have much to work with, but with decent RNG you can kill FAWs easy.
