Like every flagship Upper Deck Hockey release, the base set is the core of Series 2. It doubles the overall set size by adding another 250 cards. The first 200 are veterans not found in Series 1.
Young Guns, the popular Rookie Cards, make up the final 50. These fall 1:4 hobby packs, meaning there’s six per box. They’re definitely short prints, but at the same time attainable. At this point, Upper Deck has not a list of rookies that will be on the checklist.

Base parallels include French, hobby-exclusive Clear Cut, Exclusives (/100) and High Gloss (/10).
Inserts
UD Canvas inserts are one of the key places where Series 2 expands. Adding new base versions as well as short print subsets for Young Guns, retired players and Team Canada Program of Excellence, these combine to land four per hobby box.

UD Portraits Rookies are also 1:6 hobby packs. Continuing the numbering from Series 1, the overall set size jumps by another 50 cards. Numbered parallels for these include Gold Foil (/99) and Platinum Blue Foil (/25).
Dazzlers, which made its debut in Series 1, also gets a checklist expansion with 50 additional cards. These are among the brightest cards in the product. Blue and Pink parallels add a further chase. Orange versions are also available in retail tins.

Another place with colorful designs is Fluorescence. These come in four levels: Gold (/150), Blue (/50), Green (/15) and Magenta (/5).

2020-21 Upper Deck Series 2 isn’t all about expansion. It does have new designs as well. This includes Box Fillers, a set done on plastic stock. The theme here is hockey enforcers, both current and from the past. These are extremely tough, landing 1:359 hobby packs.

The Tampa Bay Lightning get hockey cards for their Stanley Cup celebrations in the always tough Day with the Cup (1:1,000 hobby).

Retail tins come with a pack of three O-Pee-Chee Glossy Rookies not found anywhere else. Numbering continues from Series 1, adding #11-20. Parallels include Copper (1:13) and Gold (1:50).
Series 2 does have hits. However, they’re not plentiful enough to be a box guarantee. They’re not particularly rare, either. But for those strictly chasing traditional premium hits, the focus here is different.
Memorabilia starts with Rookie Materials and Rookie Dual Materials, both of which have patch parallels.

Rookie Photoshoot Flashback Materials go back in time to players who participated in past versions of the event. These also have patch versions.

O-Pee-Chee Update
O-Pee-Chee is one of the first sets out each year. As such, the main release isn’t able to include debuting rookies. That’s where Upper Deck Series 2 comes in. Offering new cards for not only fresh debuts but vets on new teams, another 50 cards have been added to the checklist.
O-Pee-Chee Update parallels include Blue and Retro as well as hobby-exclusive Red and Retro Black Border.
Each hobby box should have at least four rookies, one veteran and one Award Winners.
