The MEGA Dream ex booster box , Japan's 2025 High-Class Pack, contains 10 packs, each with 10 cards (including a guaranteed ex card & special art/holo), featuring reprints, new "MA" rarity (English move names), and high chances for Illustration Rares (ARs) & Special Art Rares (SARs), making it a collector's dream with guaranteed pulls like 3 ARs and a Mega Attack Rare per box, unlike English sets which don't get these boxes.
