Overview
We finally have an update from Konami EU regarding the recently delayed release of Battles of Legend: Monster Mayhem, due to errors in the print run causing clumping of the sought-after Starlight Rare chase cards.
The new release date will be 28th of August 2025 in Europe, Middle East, Africa and Oceania, which means the new cards in the set will NOT BE LEGAL for play at the upcoming Oceanic and European World Championship Qualifiers.
