La criatura objetivo obtiene -X/-X hasta el final del turno. Esa criatura obtiene un -3/-3 adicional hasta el final del turno si controlabas un Hada al lanzar este hechizo.
If you controlled a Faerie as you finished casting Faerie Fencing, it doesn't matter whether you still control one as the spell resolves. The target creature will still get an additional -3/-3.
