Wizards of the Coast (WotC) announced that the Streets of New Capenna Commander Decks will have less availability in the United States and Canada on their release date due to supply chain issues.
Wizards Play Network (WPN) stores have through May 8 to schedule Streets of New Capenna Commander Launch Party events, but players should check with their local stores to confirm when they will be available. No other products from the set are expected to be impacted and more Commander Decks will be available after release.
WotC plans to release additional details on the issues sometime in the near future.
