Why Format 2?

The Original Format structure used single, uppercase letter abbreviations (ie: B) to represet each set. In 2025, with the release of the Conquest block of sets, Star Realms officially had more sets than letters in the English alphabet. We'd unfortunately outgrown the original system and a new format structure had to be established.

Wanting to retain the single, uppercase letter abbreviations, we ultimately landed on using the in-app structure of Blocks to logically break sets into groups, which would enable us to reuse letters in different groups. To identify Blocks, we simply added a prefix of a lowercase letter with a dash (ie: c-) to each group of sets.

What's Changed?

With the ability to reuse letters, some sets that had their abbreviations changed to make more logical sense. For example, it definitely was not obvious that in the Original Format that O represented High Alert Heroes.

To preserve some established legacy/familiarity, a few highly common abbreviations were kept, like V for Base Set (aka "Vanilla") and W for Colony Wars. That said, to make the system simpler and easier to learn (especially in light of the volume of sets), we did our best to primarily align abbreviations to sets by using letters that appear within set expansion symbols. For sets without letters in their symbols, we did our best to choose first letters from words in the set names.

List of abbreviation changes:

• Frontiers is now F instead of R

• Cosmic Gambits is now G (in Colonial block c-) instead of C

• Command is now C (in Colonial block c-) instead of K

• Stellar Allies is now S (in Colonial block c-) instead of L

• United Heroes is now H (in Colonial block c-) instead of U

• Frontiers Events is now E (in Frontiers block F-) instead of N

• Requisition is now R (in Frontiers block F-) instead of Q

• High Alert Heroes is now H (in Frontiers block F-) instead of O

• First Strike is now F (in Frontiers block F-) instead of S

• Command Decks is now 1 (in Commander Decks block d-) instead of D
