Released on November 28, 2025, MEGA Dream ex (M2a) is the highly anticipated year-end “High Class Pack” from the Pokémon TCG: Mega Evolution era. Sitting in the same premium lineage as sets like VSTAR Universe and Shiny Treasure ex, this set has completely redefined the modern collecting experience.
The set introduces a massive pool of 57 secret rares, including the brand-new “Mega Attack Rare” (MA) rarity, which features full-art Mega Evolutions with comic-book style English attack text. With high-value chase cards and incredibly generous box hits, MEGA Dream ex is being called one of the most exciting sets of the year. Based on box ratios and pull rate data, here is exactly what to expect.
The Best Chase Cards in MEGA Dream ex
The most valuable cards in MEGA Dream ex revolve around popular fan favorites and stunning new rarities.
The absolute crown jewel of the set is the Mega Dragonite ex Mega Ultra Rare (MUR). As the only MUR in the entire expansion, this stunning gold card is the hardest pull in the set, making it an incredibly sought-after chase card.
Beyond the MUR, collectors are aggressively hunting the Special Art Rares (SARs). The top SAR chase is the Mega Gengar ex, driven by Gengar’s massive global fanbase. Another major highlight is the Pikachu ex SAR, an adorable masterpiece illustrated by Game Freak legend James Turner, which features a pose resembling Osaka’s famous Glico Running Man. Fans of the Pokémon Legends: Z-A video game are also chasing the SAR for Canari, a fan-favorite Trainer making her TCG debut alongside her Mega Eelektross.
(Note: If you opened early boxes of MEGA Dream ex, be sure to check your Mega Attack Rares! Error versions of cards like the Mega Charizard X ex MA and Mega Gengar ex MA exist and are worth dramatically more than their corrected prints.)
Guaranteed Hit Rates in MEGA Dream ex Booster Boxes
Because MEGA Dream ex is a Japanese “High Class” set, a sealed booster box only contains 10 packs, but each pack is loaded with 10 cards. These boxes are famous for their guaranteed hit rates, making them incredibly satisfying to open.
If you open a fully sealed, untampered booster box, you are mathematically guaranteed to pull at least the following:
- 1 Super Rare (SR) or better (If you are lucky, this slot upgrades to a Special Art Rare or the elusive Mega Dragonite ex MUR!)
- 1 Mega Attack Rare (MA) (A guaranteed slot for the new comic-book style rarity)
- 1 Item-specific Super Rare
- 3 Art Rares (AR)
Some boxes have even been reported to include an additional SR or better, giving half of all boxes a bonus high-rarity hit!
MEGA Dream ex Pull Rates Chart
Using those guaranteed booster box ratios, here is the estimated hit rate per individual MEGA Dream ex booster pack:
| Card Type | Ratio | Percent Chance |
|---|---|---|
| Mega Attack Rare (MA) | 1:10 | 10% per pack |
| Art Rare (AR) | 3:10 | 30% |
| Item Super Rare (SR) | 1:10 | 10% |
| Pokemon/Supporter SR | ~1:10 | ~10% |
| Special Art Rare (SAR) | ~1:27 | ~3.7% |
| Mega Ultra Rare (MUR) | ~1:500 | ~0.2% |
(Note: Getting the Mega Dragonite ex Mega Ultra Rare is incredibly difficult. Because it is the only MUR in the set, the actual chance of hitting it is roughly 1 in 500 packs, or about 1 in every 50 booster boxes.)
Is MEGA Dream ex Worth Opening?
Absolutely! MEGA Dream ex has some of the best pull rates of any current Pokémon TCG product. Every single box delivers at least 6 guaranteed hits above standard rarity (and often more).
Between the nostalgic thrill of the new Mega Attack Rares, the beautiful SAR artwork, and the sheer volume of hits per box, this is a premium opening experience. The math makes MEGA Dream ex one of the best expected value propositions in the hobby right now.
