The XY era features several valuable sets that each contain the Generation’s uniquePokemon TCGdesigns, which set it apart from the other collections. The most valuable Steam Siege cards include a collection of Pokemon from Kalos and other famous Pokemon regions, namely Hoenn.
While you may expect to see plenty of Gardevoir cards, especially when youlook back on the Sun & Moon era, this popular Pokemon also makes its mark in X & Y. Whether you’re craving Kalos Pokemon or looking for more nostalgia, the best cards in Steam Siege have something for you.
Cards are valued according to theirTCGPlayerMarket Price,representing what you might pay on average for acopy of the cards below.
However, given their age and rarity,sale prices are vastly different depending on the card’s condition,so this market price is just a rough idea of the card’s value.
10M Steelix EX (Ultra Rare) – $4.25
Steel Yourself For More
Steelix rarely finds itself in the spotlight as one of the most valuable cards in any set, but it shows up in a big way on rare occasions like this.
The Shining SteelixfromNeo Destiny is the most valuableSteelix card ever, boasting a similarly bold gold recolor.
Unfortunately for Steelix, some of its strongest days are behind it, as it almost crossed the five-dollar mark, but recoiled and dropped into the two-dollar range beforeeventually rallying to its current price.Lightly Played (LP) and Moderately Played (MP) copies aren’t that much cheaper, so near-mint should be your target.
9Professor Sycamore (Ultra Rare) – $4.36
A Panicked Professor
Professor Sycamore is a rare Trainer to find in many sets, as he predominantly features in the XY era, with few cards displaying such a great slice-of-life moment for this Professor.
While he won’t likely find himself amongthe most valuable Trainer cards in the Pokemon TCG, Sycamore is a fun surprise to find in your Steam Siege pack.
This card captures a storyin the moment of panic on Professor Sycamore’s face, but sadly this card’s moment in the spotlight still hasn’t arrived, as it continues to bounce between three and five dollars, but it’s struggling to break out of this minimal range.
8Pokemon Ranger (Full Art) – $4.80
Even NPCs Need Love
Pokemon Ranger peeks into the top ten cards from Steam Siege, making an unexpected mark as one of the few full-art trainer cards to make it to the top.
Unfortunately for the Ranger, this card’s unique art and unlikely inclusion aren’t enough of a novelty to keep its price climbing, as it couldn’t quite break the seven-dollar barrier in recent times,falling to below five dollars.While youcan’t predict the market, this card seems unlikely to rise in value.
7Steelix EX (Full Art) – $4.95
A Darker Side To Everything
Steelix steps up its game from its initial version, showing that sometimes a step into the shadows can be exactly what you need to shine brightly. This darker look at the Steel-type snake sets Steelix apart from the less valuable EX Ultra Rare.
This card is seeing a resurgence, particularly in LP and NM conditions, as itregains crucial footing around the four-dollar mark after falling below it for a brief period.Given this card’s relatively cheap price, there’s little reason to settle for a worse copy when you have the choice to get an NM.
6Gardevoir EX (Full Art) – $5.92
The Embodiment Of Grace
Gardevoir’s first appearance in Steam Siege highlights its most quintessential depiction, as this Pokemon’s graceful elegance shines through the royal purple background. Gardevoir seems to glide across the soft background, claiming its rightful place as the sole subject.
Like many of the other cards in Steam Siege, this card’svalue took a serious hitbut has beenseeing a strong resurgenceover time. Gardevoir continues its methodical rise in price, surging from the $4.50 range up toward six dollars as it looks to catch up to its Mega Evolution.
5Mega Gardevoir EX (Ultra Rare) – $6.47
The Dark Side Of Gardevoir
The first appearance of Mega Gardevoir is an unusual one, leaning into a much darker color palette thatemphasizes this Psychic and Fairy-type Pokemon’s blue recolor.Despite the dark design choice, this card shines brightly on the price charts, maintaining a solid value.
NM copies have been rallying recently, starting around $4.50 and eventuallyjumping into the $7.00 – $7.50 range.It wasn’t able to maintain this high, falling back into the six-dollar range. You’ll have to settle for an LP copy if you want to pay less than five dollars, though.
4M Steelix EX (Full Art) – $8.54
A Golden Opportunity
Steelix slithers into the top half, solidifying its place as one of the most valuable Pokemon in Steam Siege, with three separate variations gracing the top ten. While Steelix is an unusual inclusion, especially in an X and Y set,its connection to Mega Evolution is enough to make it a major part of Steam Siege.
Steelix is creeping up in value slowly over time, roaring from the seven-dollar mark, as it aims to crack the double digits. WhileNM copies can be had for around ten dollars,this card continues to sell well, climbing up toward the $20 mark when in nearly pristine condition.
3Volcanion EX (Secret Rare) – $10.93
The Steam Pokemon Strikes
Volcanion finally makes its entrance, as this legendary Pokemon contributes heavily as a major inspiration for the Steam Siege set, givenVolcanion’s close association with steam, water, and fire.Aside from having one ofthe most powerful Water-type moves in Pokemon, Volcanion also boasts a vibrant full-art that deserves attention.
Lysandre and Volcanion share a similar fierce disposition and an intimidating red primary color palette.
Volcanion’s price varies, as the legendary Pokemon’s former high eclipsed $14, while it now barely reaches the $11 mark, falling in price if not in NM condition. While you can pick up NM copies around the market price,MP copies sell for half as much if you’re on a budget.
2M Gardevoir EX (Full Art) – $12.07
A Shiny Switch
Mega Gardevoir dances into the top two spots, sharing the glory with its twin still to come. This Shiny Mega Pokemon makes a massive statement with such stunning artwork, setting the stage for a solid future ahead for this card.
Gardevoircontinues to rise toward $13,as it looks to push further up into the teens. While this Mega Shiny Gardevoir has all the right qualities to make it a success, including an incredible rally into the double digits, it’s not enough to keep up with the most valuable Steam Siege card.
1Gardevoir EX (Secret Rare) – $32.70
A Secret Rare Art Buffet
Gardevoir claims the crown from its Mega Evolution, as it hangs onto the top spot as the most valuable card in Steam Siege despite sliding severely from its former highs.
Despite the dip,Gardevoir is a popular Pokemon that remains in high demand,so it’s not a bad idea to hold onto a Gardevoir card until it rebounds.
While its popularity often carries its cards up the charts, Steam Siege sees Gardevoir fall from the mid-40s down to the 30s, barely keeping its head above the $30 mark, which is a positive sign.NM copiesusually sell in a range between$25 to $35,so it’s worth getting the one in the best condition for a few extra dollars.
