Is Evolving Skies worth opening? Box EV and the Umbreon VMAX odds

Verdict

Not for the cards. As of mid-September 2026 an Evolving Skies booster box sells for about $2,450 and holds about $206 of expected raw card value, roughly 8 cents per dollar. It is the most expensive booster box on our sealed EV board, at more than double any other set's box, and no other set's box returns less per dollar. That price is a collector premium for a sealed, out-of-print box, not a statement about what is inside. The box also costs more than the card it is opened for: the alternate-art Umbreon VMAX #215 is about $2,283 as a single. Buy the cards you want as singles. If you want the thrill, a loose pack at about $46 is the cheapest ticket, and it is still a lottery ticket.

What Evolving Skies is

Evolving Skies released on August 27, 2021 in the Sword & Shield series (set code EVS). The printed checklist is 203 cards and the full set is 237, with 34 secret cards numbered above the printed total. It is built around Eevee's evolutions and Dragon types, and those are the cards at the top of its price list.

The rarity groups are the Sword & Shield ones: 18 Rare Holo V, 15 Rare Holo VMAX, 38 Rare Ultra (full arts, alternate-art V cards included), 22 Rare Rainbow (in this data, alternate-art VMAX cards included) and 12 gold Rare Secret cards, above 132 Commons, Uncommons, Rares and Rare Holos.

Pullnomics tracks the booster box (36 packs), a half booster box (18), two Elite Trainer Boxes (nine packs each), two Pokémon Center Elite Trainer Boxes (11), a Build & Battle Box (four), sleeved and loose booster packs, and one-pack and three-pack blisters. All of it is out of print, so every price carries that collector premium.

The numbers

The block below shows today's headline figures from the Evolving Skies set page.

The median card is worth about 43 cents. Forty-seven cards clear $10 and 18 clear $50. A copy of every card at market runs about $8,195.

Almost all of that sits in two rarity groups. The 22 Rare Rainbow cards and 38 Rare Ultra cards hold about $7,865 between them, about 96 percent of the set. The other 177 cards add up to about $330. Umbreon VMAX #215 alone is about 28 percent of the set's value, and with Rayquaza VMAX #218 it is 43 percent.

Sealed EV by product

Sealed EV prices the average contents of a product at today's TCGplayer market; the methodology has the formula. Every Evolving Skies pack has the same EV, about $5.73, the highest per-pack figure of any booster box on the sealed EV board. The cards are not the problem; the pack price is.

The booster box works out to about $68 per pack and an EV ratio of about 0.08, with a net EV of about $158 once a 15 percent marketplace fee and $1 shipping per card worth $1 or more come off. A typical booster box across the board returns roughly 30 to 35 cents per dollar, and the other Sword & Shield boxes on the board return roughly 11 to 27 cents.

The box is also not the cheapest way to buy packs. The art bundle of four loose packs (about $173) is about $43 per pack, a ratio of about 0.13 and the best in the set. A single loose booster pack is about $46 (about 0.12). The cheaper Elite Trainer Box (Glaceon, Vaporeon, Sylveon and Espeon, about $507) is about $56 per pack (about 0.10), and the other one (about $566) about $63. The worst products in the table are the Pokémon Center Elite Trainer Boxes: about $1,089 and $1,109 for 11 packs, about $100 per pack, a ratio of about 0.06.

So the best product to open is loose packs, and the box sits in the bottom half of the table, because the sealed box is itself the collectible.

Chase share is about 43 percent, which understates how narrow this set is. About $3.42 of each pack's $5.73 comes from twelve alternate-art cards, and about 92 cents comes from the Umbreon VMAX alone.

Chase cards

These are the eight most valuable cards in the set right now.

Umbreon VMAX #215, the card collectors call Moonbreon, is about $2,283. Rayquaza VMAX #218 is about $1,255, Dragonite V #192 about $523, Rayquaza V #194 about $494, Leafeon VMAX #205 about $410, Umbreon V #189 about $386, Sylveon VMAX #212 about $384 and Glaceon VMAX #209 about $313. The next four, Espeon V, Sylveon V, Glaceon V and Leafeon V, run from about $241 down to about $151. All twelve are alternate arts, and together they cost about $6,800, 83 percent of the set.

The same Pokémon in the same rarity group can be a different card entirely. The rainbow Umbreon VMAX #214 is about $84 against $2,283 for #215. Rayquaza VMAX #217 is about $112 against $1,255 for #218.

That is why the group averages mislead. Rare Rainbow cards average about $232, but seven of them hold about $4,841 of the group's $5,111, and the other 15 average about $18. Rare Ultra has the same shape: outside its top eight, the other 30 cards average about $17. Pulling a Rare Rainbow usually means a card worth about $18.

Pull rates

The rates below were measured for Evolving Skies itself, not taken from a Sword & Shield era average. Each is the midpoint of published pack-opening counts gathered in September 2026, and the methodology names the sources.

A 36-pack box averages four Rare Holo V cards, about two VMAX cards and about one Rare Ultra. A Rare Rainbow, at 1 in 113 packs, shows up in only about 27 percent of boxes. About 81 percent of boxes contain at least one Rare Ultra or better, so roughly one box in five holds nothing above a regular VMAX.

The published Sword & Shield rates group cards by printed rarity, and alternate arts have no separate published rate. In this set's data the alternate-art V cards sit inside Rare Ultra and the alternate-art VMAX cards inside Rare Rainbow, and the EV treats each one as equally likely as any other card of its group. So the true odds of a specific alternate art are much longer than the group's headline rate. With 22 Rare Rainbow cards at 1 in 113, a specific one is about 1 in 2,486 packs on that equal assumption. That is about 69 booster boxes, roughly $169,000, for a card that costs about $2,283. A specific Rare Ultra such as Dragonite V is about 1 in 1,400 packs.

If alternate arts are in fact scarcer than the other cards in their groups, the real odds are longer still and the $5.73 pack EV flatters the set.

Who should open it and who should buy singles

If you want Umbreon VMAX, or any one alternate art, buy the single. The box costs more than the card and gives you, on the generous assumption, about a 1 in 69 chance of pulling it.

Set builders should go to singles too. The $8,195 cost of one of every card, spent on boxes, buys about 120 packs: on average about one Rare Rainbow of 22 and about three Rare Ultras of 38.

If you play, nothing here needs sealed product: the Rare Holo V cards average about $2.31.

If you want the experience, buy a loose pack or two, expect about $5.73 of cards from each, and know that about 95 percent of packs hold nothing above a regular VMAX.

If you already own a sealed box, opening it trades a $2,450 collectible for about $206 of expected cards.

How to buy it cheaper

Each Evolving Skies card page and sealed product page carries the TCGplayer market price, its history, the price that would be 12 percent below market, and two eBay buttons. The first opens an eBay search restricted to Buy It Now listings from US sellers, with proxies, lots, code cards and look-alike products filtered out, sorted by price plus shipping and capped at 12 percent under market. The second is the same search with no cap. Both are affiliate links. The block below links to eBay searches for the main Evolving Skies sealed products, each already capped under its below-market price.

That cap covers the item price only, so add shipping yourself. Only a landed price, item plus shipping, that is 12 percent or more under market counts: about $2,156 delivered for the booster box. Ignore any seller "was $X" markdown. An empty capped search means no listing sits below market right now. Switch to the uncapped button to see every live price, and turn on eBay's own "Save this search" so eBay emails new matches.

With singles, keep in mind that every card price on the site is raw Near Mint. The Deal Score method on the methodology page values a Lightly Played card at 85 percent of that, so a Lightly Played Umbreon VMAX #215 qualifies near $1,708 landed, against about $2,009 for Near Mint. The same method treats a landed price under 10 percent of market, about $228 for this card, as a mismatch or a scam, not a bargain. In the US, eBay's Authenticity Guarantee applies to trading cards sold for $250 or more, which at market price takes in the top eight cards here. Graded copies are not scored by the method; raw vs graded explains the gap.

Bottom line

Evolving Skies has the most valuable packs of any booster box on the board and the lowest EV ratio of any set's box: about $5.73 of expected cards in a pack that costs $46 to $68, and about $206 in a box that costs about $2,450. Twelve alternate arts carry the set, no published rate says how rare each one really is, and even the generous assumption puts Umbreon VMAX at about 1 in 2,486 packs. A pack is a lottery ticket you open for fun. For the cards themselves, start at the Evolving Skies set page, open the card you want and press its first eBay button to see whether any copy is listed under market today.
