Mega Symphonia (M1S), released alongside Mega Brave, marks the highly anticipated beginning of the brand-new Pokémon TCG: Mega Evolution era. Paralleling the excitement of the Pokémon Legends: Z-A video game, this set has taken the hobby by storm by officially reintroducing the fan-favorite Mega Evolution mechanic.
Because this expansion introduces a completely new rarity tier and features massively popular Pokémon like Mega Gardevoir, Mega Latias, and Mega Kangaskhan, Japanese booster boxes are in incredibly high demand. But before you pay a premium for these highly sought-after packs, you need to know: how good are the pull rates?
Based on aggregated community data and thousands of booster box openings, we have broken down exactly what to expect.
The Best Chase Cards in Mega Symphonia
Unsurprisingly, the most valuable cards in Mega Symphonia revolve around the stunning new Mega Evolution designs.
The absolute crown jewel of the set is the Mega Gardevoir ex Mega Ultra Rare (MUR). This expansion introduced the MUR rarity — a brand-new style of gold card that features completely unique artwork rather than just being a gold version of a standard full art. Because the MUR is so difficult to pull, it has quickly become one of the most expensive chase cards of the new era.
Guaranteed Hit Rates in Mega Symphonia Booster Boxes
Because Mega Symphonia is a standard Japanese main expansion, a sealed booster box contains 30 packs (with 5 cards per pack). While standard sets operate differently than “High Class” sets, these boxes are still loaded with guaranteed hit rates to ensure a satisfying opening experience.
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 Ultra Rare!)
- 1 Item-specific Super Rare (A guaranteed Trainer SR slot)
- 3 Art Rares (AR)
- 4-5 Double Rares (RR)
Mega Symphonia Pull Rates Chart
Using those guaranteed booster box ratios and aggregated community data, here is the estimated hit rate per individual Mega Symphonia booster pack:
| Card Type | Ratio | Percent Chance |
|---|---|---|
| Double Rare (RR) | ~1:7 | ~14% per pack |
| Art Rare (AR) | 1:10 | 10% |
| Item Super Rare (SR) | 1:30 | 3.3% |
| Pokemon/Supporter SR | 1:39 | ~2.5% |
| Special Art Rare (SAR) | ~1:105 | ~0.9% |
| Mega Ultra Rare (MUR) | ~1:1650 | <0.1% |
(Note: Getting a Mega Ultra Rare or Special Art Rare is incredibly difficult. Because they share the same guaranteed slot as the standard Super Rares, you will average about 1 SAR every 3.5 booster boxes, and the massive MUR chase card only appears in roughly 1 out of every 55 boxes.)
Is Mega Symphonia Worth Opening?
Absolutely! No matter which Mega Evolution you like the most, this set is a fantastic way to kick off the new era. Because every box guarantees both a Pokémon/Supporter SR and a dedicated Trainer Item SR, the pull structure feels highly rewarding.
Pulling fresh, textured Art Rares and experiencing the brand-new glitter layer on full arts makes the opening experience incredibly fun. Plus, there is always the legendary chance to beat the odds and pull the 1-in-55-box Mega Gardevoir ex MUR!
