A decade before “Endless Eight” there was “Sakura’s Never-Ending Day”. The episode starts out normally enough, with Sakua’s dad being a guest teacher. Some shows (Including The Simpsons) would play “parent teaching kid’s class” for embarassment, but this isn’t your typical show, and Sakura beams with pride at her dad’s academic prowess. He also enthralls Syaoran with his lecture on ancient Egypt—only for Syaoran to learn whose dad he is!
The next day, Sakura has a recorder test for which she didn’t prepare. She messes up a bit but Tomoyo encourages her and she gets through it without being expelled or barred from future employment. While she celebrates that night with her dad and brother (who also had an exam that day) she’s frustrated when she goes to bed, only to be awoken at midnight by the bell of the school’s clock tower—unheard of at such an hour.
The next day, the events of the previous day repeat, and the only she seems to notice. Since she practiced the part she messed up on, she does better at the recorder test, but having to take the test again still sucks. Syaoran ends up kicking an errant soccer ball into goal from fifty yards away, but in a different way, as he too notices things are repeating and concludes it’s a Clow Card.
That night, donning a the green and yellow fairy-style battle costume (which we first saw at Tomoyo’s house in the previous episode) Sakura takes flight and heads to the bell to secure the card, only for it to slow her and Kero-chan down to a claw (resulting in some distorted voices). When midnight strikes the day rewinds once more.
After living the same day a third time, Sakura, Kero and Tomoyo return again that night and encounter Syaoran there, who suggests a stealthier approach. I figured Shadow would come into play, but instead Sakura sneaks closer to Time and casts Shield to protect her from its time magic.
After a short chase, it’s Syaoran who manages to trap Time from escaping with his lightning magic, so that even when Sakura secures the Clow Card, it passes her over and flies into the hand of a very smug Syaoran, it’s new rightful owner due to a technicality.
Frankly, Syaoran needed a win in order to remain credible as, you know, an actual rival to Sakura as opposed to a guy who always gets the short end of the stick as comeuppance for his Sakura-negging. On the other hand, Time seems like a pretty powerful card that Sakura doesn’t have, and one he could use to collect more cards.
All that said, there can only be one Cardcaptor, and Sakura is the one with the staff. That, combined with the fact Sakura has a huge lead and many powerful cards at her disposal, means the two had better get used to cooperating in order to collect all the cards in an efficient manner.
On that note, as day-repetition episodes go, this was efficient yet satisfying, providing just enough of the temporal weirdness without overplaying the gimmick. It helped that Sakura understood what was happening pretty quickly and didn’t have to convince Tomoyo or anyone else. Sure, it could have been stretched across eight episodes and over 15,000 repetitions…but there’s other cards to capture!
