A Lorcana Pack Rush event is a fun, casual format where players use just two booster packs to build a deck on the fly, without ink color restrictions, aiming for 15 lore to win, and it's a popular way for local game stores (LGS) to host prereleases and distribute new sets, often with extra prizes. Players open two packs (48 cards total), set aside the puzzle/marketing cards as starting ink, shuffle the rest into a 24-card deck, draw 5, and play. It's a low-pressure way to get new cards and learn the game, perfect for all skill levels.
