Seasonal banners (Winter, Summer, Halloween) appear during those special occasions, while festival banners (FFBE, Crystal Warriors) appear when a new unit in the same line gets released.
Both types feature limited-time units and often include rate ups for the old characters of the same line when they appear.
*Salire (Sweetheart) is not a limited unit in GL.
