2023-24 Upper Deck Series 1 Hockey hits the ice with some new content and format tweaks. Of course, the set boasts the next round of Young Guns rookie cards.

Per UD, "For the first time in more than 20 years, the configuration of our flagship Upper Deck Series will see a refresh that will include notable changes to deliver an even more compelling collecting experience."

This includes an updated Hobby format with 12 cards per pack and 12 packs per box (144 cards total) to replace the standard eight cards per pack and 24 packs per box (192 cards total). Every pack now has an average of three inserts instead of one.

Brand staples Young Guns and UD Canvas are found at the same rate per Hobby box, still averaging six Young Guns and four UD Canvas cards, despite having new pack odds.

Upper Deck also noted that the same "refresh" applies to 2023-24 Upper Deck Series 2 Hockey and 2023-24 Upper Deck Extended Series Hockey.
