Anastasiya does sound mystical, but it's too common in Russia. Almost a stereotypical Russian female name.
How about:
Aelita (Аэлита)
Apollinariya (Аполлинария)
Doroteya (Доротея)
Elikonida (Еликонида)
Elvira (Эльвира)
Esfir (Есфирь, Эсфирь)
Evdokiya (Евдокия)
Kazimira (Казимира)
Renata (Рената)
Serafima (Серафима)
Severina (Северина)
Snezhana (Снежана)
Vladimira (Владимира)
Zinoviya (Зиновия)
Some are rare or a bit strange, but they're all Russian names, and all usable.
