The first two episodes are already out on Crunchyroll and Hulu, though you have to pay to watch them right when the episodes come out. For free users, you'd have to wait 19 days after the episodes get uploaded to watch for free (legally), though there's also Youtube and kissanime for those who don't really care about watching the show legally.
New episodes are out every Sunday at 7:30 am JPT on NHK BS Premium and is simulcasted on Crunchyroll by 5pm PST every Saturday (since it's still Saturday in the US at the time that new episodes are airing in Japan)
Anyway, the animation quality of Clear Card is top notch, the CGI is on point (
take fucking notes, Toei), they kept the music from the original series (like Hontou no Ichiban, aka the instrumental/orchestral version of Platinum) while also creating new music that fits perfectly well and doesn't sound out of place at all (like the new music when Sakura secures a new card), AND I love that they're following the manga closely while still making small adjustments for anime continuity
