I very much like this card as a 1- or 2-of in Hoshiko Shiro: Untold Protagonist lists. If your opponent isn't playing some nonsense glacier protect-every-central-server jank, Jak gives you a minimum of 1 Archives access each turn, keeping your Magic Girl mode permanently activated. Paired with DreamNet, this can turn into a pretty powerful card draw engine. Additionally, this card can make Fencer Fueno an even stronger asset spam removal tool than it already is. Overall, I think I play this card more than I should, but I still think more people should be playing it.
