Is Mega Evolution worth opening? EV, pull rates and chase cards

Verdict: a qualified open, and the best of the four recent sets covered in these guides for someone who wants to rip a Mega-era product. A Mega Evolution booster box sells for about $315, the Enhanced Booster Box about $289, and the cards inside are worth about $110 at raw market, an EV ratio of roughly 0.35 to 0.38. Those are ordinary numbers for a modern box, but the value here is spread across ten Special Illustration Rares averaging about $84 and two Mega Hyper Rares averaging about $220, with nine cards in the set worth $50 or more. You still lose money on paper with every box, so players and set collectors should buy singles. If you are going to open something, the Enhanced Booster Box bought below market is the pick.

What Mega Evolution is

Mega Evolution (set code MEG) released on September 26, 2025 and opened the era of the same name, bringing Mega ex Pokémon back to the game. It is a full-size set: 132 cards in the printed numbering and 188 in total. Double Rares are the Mega ex cards in their regular frames, Ultra Rares are the full-art versions, Illustration Rares are alternate-art single Pokémon, Special Illustration Rares are alternate-art ex and Supporter cards, and the two Mega Hyper Rares are the gold cards at the very end of the numbering.

Here is where the set stands today.

All 188 cards are priced. The median card is about $0.29, 19 cards are worth $10 or more, and nine are worth $50 or more. The whole set at market adds up to roughly $1,570.

The chase cards

Here are the most valuable cards in the set right now.

The top of the set is a tight cluster rather than one runaway card. Mega Lucario ex #188, the Mega Hyper Rare, is about $248; Mega Gardevoir ex #187, the other Mega Hyper Rare, about $195. The Special Illustration Rares of the same two Pokémon, Mega Lucario ex #179 and Mega Gardevoir ex #178, are about $184 and $177, and Mega Venusaur ex #177 is about $154. Below them, Mega Latias ex #181 is about $77, Lillie's Determination #184 about $65, Mega Kangaskhan ex #182 about $57 and Mega Absol ex #180 about $52.

The ten SIRs average about $84 and the two MHRs about $220; together those twelve cards make up roughly $1,280 of the set's $1,570 total, so the value is still concentrated in the top rarities, but not in any single card. Seven of the ten SIRs are worth about $50 or more. The 22 Illustration Rares average about $6.50, led by Vulpix #138, Bulbasaur #133 and Ivysaur #134 at about $19 to $20. The 22 Ultra Rares average about $4.80 and the ten Double Rares about $0.89.

Pull rates and what "1 in N" means

These are the published pull rates for the set, in packs per hit.

Double Rares come about once every 5 packs, Illustration Rares once every 9, Ultra Rares once every 12.5, Special Illustration Rares about once every 101 packs, and Mega Hyper Rares about once every 1,260. Roughly 1 pack in 5 (0.191) contains a hit of Illustration Rare quality or better.

Over a 36-pack booster box, that works out to about seven Double Rares, four Illustration Rares, three Ultra Rares, and about 0.36 Special Illustration Rares. Put differently, only around three boxes in ten contain an SIR, and you would open about 35 boxes on average to see a Mega Hyper Rare. Ten SIRs share that 1-in-101 slot, so if they are equally likely, any particular one, say the Mega Lucario, is about 1 in 1,010 packs, or about 28 boxes.

An Elite Trainer Box has 9 packs: expect one Illustration Rare, under one Ultra Rare, and roughly a 9% chance at an SIR. The model gives the ETB an 85% chance of at least one hit of any kind; the missing 15% is an ETB that returns nothing better than a Double Rare.

Sealed EV

Here is the expected value of each Mega Evolution product against its current market price.

EV ratio is gross EV divided by market price. Net EV is what you would clear after selling: a 15% marketplace fee and $1 shipping per card worth at least $1 come off, and cards under $1 count as bulk at about two cents. Chase share is the fraction of hit EV that comes from SIRs and Mega Hyper Rares.

The per-pack EV is about $3.04. For the regular booster box: market about $315, gross EV about $110, net EV about $71, ratio about 0.35. The Enhanced Booster Box holds the same 36 packs but sells for about $289, so its ratio is about 0.38, the best of any product for this set. The break-even box price, where gross EV equals price, is about $110 either way, so each box opened at market is a loss on paper of about $180 to $205 at gross EV. A loose pack at about $8.55 has a ratio of about 0.36, and the four-pack art bundle about 0.35; those are unusually close to the box, which means there is little penalty for opening a handful of packs instead of a whole box.

Further down the list, the Mega Heroes mini tins at about $19 to $22 are 0.27 to 0.32, the booster bundle is about 0.29, and the regular Elite Trainer Boxes at about $123 to $127 are about 0.22. The Pokémon Center exclusive ETBs at about $185 and $220 are 0.15 and 0.12, and the premium checklane blisters at about $27 to $31 are around 0.10. Skip the Build & Battle display and the mini tin display, both priced as retail displays rather than as packs.

The chase share is about 0.44, meaning less than half of the hit value depends on the two rarest slots. Illustration Rares and Ultra Rares carry the rest, which is why a box with no SIR in it still returns cards worth roughly $70 at raw market rather than next to nothing.

Who should open this

Players: no. Double Rares average under a dollar, and even the full-art Ultra Rares average about $4.80. Buy the deck cards as singles.

Set collectors: mostly no. Everything below Special Illustration Rare is cheap; you can assemble the commons through Ultra Rares for a fraction of a box. The twelve top cards are the expensive part, and at about $1,280 combined they cost less than the roughly 28 to 35 boxes it would take on average to pull any one specific chase card.

Chase hunters: this is the set where it makes the most sense among the four, because there are ten SIRs worth pulling instead of one. A box has about a 30% chance of an SIR, and the SIR you hit is worth about $84 on average, with four of the ten at $77 or more. The math is still against you at 0.38, but the downside is softer.

People who like ripping packs: yes. The Enhanced Booster Box at about $289 is about $110 cheaper than the Phantasmal Flames box and carries the better ratio of the two Mega-era sets covered in these guides.

How to buy it cheaper

The site rescans eBay every 15 minutes for Mega Evolution sealed listings that land at least 12% below TCGplayer market once shipping is included. These are the current ones.

Set an alert at /alerts?set=me1 for the products you want. Compare the landed price, item plus shipping, against the market price for that exact product; the Enhanced Booster Box and the regular box are listed separately for a reason, and the two ETB versions carry different prices. A box at 12% below the Enhanced Box market brings the ratio to about 0.43. The scoring rules are on /methodology and every product for this set is listed on /sets/mega-evolution.

Bottom line

Mega Evolution is the most reasonable of the four recent sets to open: a ratio of about 0.35 to 0.38, ten Special Illustration Rares that average about $84, and a chase share of about 0.44 that keeps a no-SIR box from feeling empty. It is still a loss on paper, every box, by about $180 to $205 at gross EV, so buy singles if the goal is the cards. If the goal is to open packs, choose the Enhanced Booster Box, buy it below market, and set your expectations at roughly one SIR every three boxes.
