Upper Deck Synergy 2021 Hockey — Checklist & Parallels

The full 2021 Hockey Upper Deck Synergy checklist — 927 cards with 1 base parallels and 32 insert sets — plus the eBay item specifics that matter and how to list them fast.

Upper Deck Synergy 2021 Hockey parallels

Parallels are the colored and serial-numbered versions of each base card. This checklist includes:

• Base - #/12 /12

When you list, put the exact parallel name in both the title and the Parallel/Variety item specific — a "Silver" listed as just a base card gets buried under cheaper copies.
