Managed to pull a +Spd L!Julia, which allows me to fix my +HP/-Atk one, and brings me one step closer to speedy Julia. Now do I stick with Swift Sparrow 3 or sacrifice Bernadetta for Atk/Spd Push 4.
This is the build. Atk/Spd Oath will probably be switched out for Joint Drive Atk if I get a second Lilith, and Sol is generally Glimmer. Only took a L!Celica and a Bernadetta, but now I only really need merges.
