Pokémon Card Game Mega Dream ex (M2a) – Japanese Booster Box

The MEGA Series gets its High Class showpiece.

Mega Dream ex (ハイクラスパック MEGAドリームex / M2a) is the 2025 Japanese High Class Pack for the MEGA Series, following core expansions like Mega Brave, Mega Symphonia and Inferno X. It acts as a premium recap and upgrade set, reprinting key cards from Paradise Dragona through Inferno X while introducing new chase cards and a brand-new rarity

Each Japanese booster box contains 10 packs, and each pack holds 10 cards, with the classic High Class feel – multiple holos per pack and strong hit density

Mega Dream ex introduces:

• A new rarity, MA (Mega Attack Rare), featuring comic-style action text and bold, full-frame art that pays homage to classic XY Mega designs.
• A huge 193+ card set list packed with iconic Mega Pokémon and competitive reprints, including cards that saw heavy play in the 2024–2025 season.
• Multiple mirror foil patterns (Energy symbols and various Poké Ball designs), giving collectors a deep chase even at lower rarities.

Headline chase cards (based on current reveals and market hype) include:

• Mega Gengar ex – Special Art Rare (SAR) – already shaping up as the iconic ghost chase of the set.
• Lillie’s Resolve – SAR (new artwork) – an alternate illustration version of a consistently high-demand Supporter.
• Mega Charizard X ex – MA (Mega Attack Rare) – a marquee MA card combining Charizard popularity with the new rarity.

As with past High Class Packs like Terastal Festival ex, boxes are expected to deliver strong pull rates, excellent Japanese print quality, and long-term sealed appeal. For collectors who already love Mega Brave / Mega Symphonia / Inferno X, Mega Dream ex is the natural “best-of plus” upgrade — a premium way to round out the MEGA era playables and chase some of the most hyped SARs of 2025.
