The ogcds with aetherflow as well.(Indom,energy drain,bane,excog, lustrate,). Don't forget the other things the fairy can do well. Fey covenant for the magic defense up(which decreases damage by 8-9 percent in total) and fey illumination for increased healing and fey union when there's autos or a bleed going out on one person. The main weakness for the sch is sustained aoe healing given that indom is a 30 sec cd gated by aetherflow and emergency is 20 seconds but it can easily be covered by the other healer. The utility with ogcds, their personal damage, chain strat, and the fairy and its abilities put it ahead of the bigger shields and the rng nature of the cards that noct astro can do.
