Yep, it depends on what's in it. If it has Halloween Nowi and Jakob, I'd definitely summon. I want to replace their bad ivs lol. Besides the Spring Banner is available for a whole month.
Depends what's in it, only ones we know are LIke, Gunnthra, Fjorm and the remaining summer and performer units. (Which are S Elise, S Tiki, and PA Shigure of I remember correctly) And of course the new legendary hero, who ever that is.
