M5 Abyss Eye is built around Mega Darkrai ex and M6 Storm Emeralda around Mega Rayquaza ex, each printed as a Special Art Rare and a Mega Ultra Rare. Community-reported pull-rate estimates put the two sets at roughly the same odds, so the choice comes down to which Mega ex you want.

The Chase Card Showdown: Mega Darkrai ex vs Mega Rayquaza ex
Each set builds its entire secret-rare tier around one Pokemon printed twice — once as a Special Art Rare, once as the set’s top Mega Ultra Rare. Here’s what each one actually does on the field:
| Card | Number | Rarity | Set | Highlights |
|---|---|---|---|---|
| Mega Darkrai ex | 114/118 | SAR | M5 Abyss Eye | 280 HP, Darkness · “Night Raid” for 110+ damage · “Abyss Eye” can instantly knock out the opponent’s Active Pokemon under a special condition |
| Mega Darkrai ex | 118/118 | MUR | M5 Abyss Eye | Same 280 HP stat line as the SAR print, in the set’s top Mega Ultra Rare treatment |
| Mega Rayquaza ex | 110/076 | SAR | M6 Storm Emeralda | ¥138,000 (~$850), day-one Japanese secondary-market price |
| Mega Rayquaza ex | 113/076 | MUR | M6 Storm Emeralda | ¥298,000 (~$1,830), day-one price — the gold top card of the set |
Mega Darkrai ex’s calling card is its kit — a 110+ damage attack backed by a special-condition instant knockout, the kind of card built for the table as much as the binder. Mega Rayquaza ex’s calling card is the number, with day-one Japanese secondary-market prices from our own release coverage. Secondary prices move fast in the first weeks after any set drops, so treat them as a snapshot rather than a floor.

Pull Rates: What the Community Data Says
Neither set has official pull rates published by The Pokemon Company — nobody does, for Japanese sets. What exists is community-reported, aggregated opening data across the recent MEGA-series releases, M5 Abyss Eye included, and it points to a consistent pattern across both boxes:
| Rarity tier | Estimated rate per box | What that means |
|---|---|---|
| SAR Special Art Rare | ~1 per 2–3 boxes | Roughly a coin flip per box, either set |
| MUR Mega Ultra Rare | ~1 per 50–100 boxes | Case-level odds, not box-level, either set |
This is the same MEGA-series estimate published in our M6 release coverage, and it was built in part from Abyss Eye opening data — so the same rough odds apply whether you’re chasing Mega Darkrai ex or Mega Rayquaza ex. The practical read: a single box of either set gives you a realistic shot at the SAR print, and no realistic shot at all at the MUR. If the MUR is the actual goal, buying single boxes is the wrong tool for the job regardless of which set you pick.

The Price Gap
The M5 Abyss Eye booster box is currently listed as a Sealed option at ¥9,818 (~$64) and a No Shrink option at ¥8,155 (~$53). The M6 Storm Emeralda booster box is currently listed as a Sealed option at ¥10,150 (~$66); the M6 No Shrink option is sold out at the time of this update — sourcing requests go through Quick Order.

Abyss Eye or Storm Emeralda: Which Box to Buy
Both boxes are defensible buys. Which one makes sense depends on what you’re actually after:
- You want Mega Darkrai ex specifically. M5 Abyss Eye is the set built around it — its SAR and MUR prints both live here. It is also the lower-priced of the two Sealed booster box options.
- You want the single highest-ceiling card in the current MEGA lineup. M6 Storm Emeralda is home to the Mega Rayquaza ex MUR. The odds are still roughly 1-in-50-to-100 per box either way — you’re buying a shot at a bigger number, not better odds.
- You’re budget-conscious or testing the format for the first time. M5 Abyss Eye is the lower-priced entry of the two.
- You can’t decide. Because the two headline Mega ex are different Pokemon in different card-power lanes (a tanky special-condition attacker versus one of the franchise’s most recognizable Legendaries), a reasonable split is one box of each rather than doubling up on either.
