BBM continued their tradition (since 2012) of issuing two sets featuring the cheerleaders for NPB teams. The two sets came out about a month apart from each other, and are both pack-based, with 87 cards in the base checklist. I don't believe there are any cheerleaders that appear in both sets; I can't really completely verify this easily right now. I'm posting these together because they function as two series of the same release, essentially, they came out very close together, and I'm still way behind on posts.
Nine teams are found in the sets, though the number of cards per team ranges from 7 to 13.
As always, autographs can be found; most cheerleaders have 60 copies per card, though at least one has 59 (oops, she lost a sticker?). Also, there are five polaroid "cheki" autographs for each one. Finally, a few dual-cheki cards (not really cards, just pictures) were inserted in packs.
I will say that this continues to be one of the most popular releases of the year. Finding full sets at reasonable prices isn't easy; I have my Mai set but no Hana yet. I can't justify paying $26 for a 90-card set of base cards. By comparison, most 81-card team sets can be found for $5-10 if you look hard enough - the notable exception being the BayStars, which typically run $15 or more. (WHY!?)
Anyway, it's a good-looking set, in terms of subject matter, photograph quality, and design.
