8Pikachu ex (Gold Ultra Rare)
Price: $38
Golden-hued Ultra Rare cards tend to be extremely valuable in any set and this is also the case inTerastal Festival Ex, according toPokebeach’s market research.The Gold Ultra Rare version of Pikachu ex is one of the most valuable in the set with an estimated price of $38.The card’s rarity and subsequent golden design play an incredible role in its high market value, but this is a genuinely strong card forPokémon TCGplayers to have, too.

Leafeon ex also stands out due to its gameplay value.

Its second move deals 230 damage to the opponent’s active Pokémon but, on top of that, also restores 100 HP for each of the player’s Pokémon on the bench.With all of this, Leafeon ex costs around $39.
6Glaceon ex (Special Illustration Rare)
Price: $44
Another Eeveelution is listed among the most expensive in theTerastal Festival Exset: Glaceon ex’s Special Illustration Rare version. This card has an incredible gameplay value. Its first attack, costing two Energies, deals 110 damage to the active opponent, plus 30 damage to any Benched Pokémon. This is where Glaceon ex’s second attack comes into play. For three Energies,Glaceon can instantly Knock Out any opponent’s Pokémon with six damage counters. If Glaceon uses its first attack and targets a benched Pokémon card twice, it can instantly have them Knocked Out, without having to fully deplete its HP.
If the targeted benched card is a Pokémon ex, they can net two Prize cards with little work.
In addition to just how strong Glaceon ex can be if the proper strategy is pulled off – and provided it isn’t Knocked Out before its third turn – this rare Special Illustration Rare card inPokémon TCGalso has a great piece of artwork accompanying it. The creature is posed at the center of an elaborate ice-themed tapestry that makes remarkable to players and collectors alike.Pokebeach’s research shows that Glaceon ex costs around $44.
5Espeon ex (Special Illustration Rare)
Price: $46
The next expensive card on theTerastal Festival Exlist is the Special Illustration version of Espeon ex.Pokebeachmentions thatEspeon ex is worth around $46. As a Special Illustration Rare card, this is naturally a rare one to obtain, but it is also great in gameplay. The first attack sees Espeon ex deal 160 damage to the opponent’s active Pokémon and randomly discard a card from their hand, which could disrupt potential strategies and strong cards. Espeon ex’s second move is a scary one.
With it, the player can force the opponent to devolve Evolved Pokémon by returning each of their highest Stage Evolution cards from the bench into the deck, which can result in Knock Outs depending on how many damage counters some creatures already have. Aside from the possible game-winning scenario it may create,Espeon ex can effectively reset a player’s board inPokémon TCG, which makes its usage in the late game a force to be reckoned with.
4Sylveon (Master Ball Reverse Holo)
Price: $62
Rarer than most cards in the entire set is Sylveon’s Master Ball Reverse Holo.This card’s price is estimated at around $ 62, according toPokebeach. Sylveon’s special card is expensive thanks to its high rarity, but even more expensive than most other Eeveelution Master Ball Reverse Holos because this is a fan-favorite creature, as mentioned by the outlet. Sylveon’s esteem as one of the top Eeveelutions in the community is what grants this card its price.
Even if cut within the traditional card’s frame, Sylveon’s Master Ball Reverse Holo also has a delightful illustration, showing the Fairy-type standing peacefully on top of the water as pink petals surround it. ThisPokémon TCGcard’s main flaw is not having a larger and more complete artwork showing the rest of the scenery like theimmersive cards inPokémon TCG Pocket.
3Sylveon ex (Special Illustration Rare)
Price: $72
More valuable than its rarer version is Sylveon ex. This newTerastal Festival Excard combines the aforementioned fan-appreciation factor with a powerful card to wield in gameplay.Sylveon ex’s first attack deals a massive blow of 160 damage and, additionally, forces the Defending Pokémon to deal 100 less damage on the opponent’s next turn.
The 100-damage reduction takes place before calculating Weaknesses and Resistances.
With its second move, Sylveon ex allows players to select two of the opponent’s benched Pokémon and shuffle them and their attached cards back into the deck. This attack can’t be used if the same type of move was used on the player’s last turn. Nevertheless, like Espeon ex, Sylveon ex can disrupt an opponent’s entire strategy, even if they are not focused on dealing damage. Essentially, Sylveon ex can protect the player in two different ways.Pokebeachstates that this card is worth approximately $72.
2Umbreon ex (Special Illustration Rare)
Price: $216
The second-most expensive card in theTerastal Festival Exset is Umbreon ex.Evaluated at around $216, according toPokebeach, this item takes a massive leap in terms of price compared to the previous card. Umbreon ex is the perfect blend of incredible gameplay value, superb artwork, fan adoration, and rarity. Its first attack deals 160 damage to the opposing Pokémon and leaves them Confused, which is a great way of potentially avoiding damage. The second attack, which costs three Energies, forces Umbreon ex to discard all Energy and draw a Prize Card.
Pokémon TCG: Why This Newly Revealed Terastal Festival Secret Rare Is Perfect For Collectors & Competitive Players
A new secret rare card has been revealed for the Terastal Festival Pokemon TCG set, and it features incredible work by an iconic manga artist.
This attack does not deal damage or do anything else, but it could be a way of ending a match near its late stages. When it comes to its illustration, Umbreon ex stands out due to how elegantly designed it is. Furthermore, its artwork resembles theMoonbreon card inPokémon TCG, one of the most expensive prints of Umbreon ever made. Additionally,Umbreon is informally recognized as the favorite Eeveelution among the community, which just helps its price skyrocket.
1Umbreon (Master Ball Reverse Holo)
Price: $242
The most expensiveTerastal Festival Excard is Umbreon’s Master Ball Reverse Holo. This is a result of Umbreon being both a fan-favorite among all the Eeveelutions, but also its high rarity that is harder to obtain than a Secret Illustration Rare.The card’s artwork shows Umbreon sitting on a window sill and looking at the moon outside in a delicate piece of artwork, even if it is cut within the traditionalTCGframe.
While this Umbreon card is just as rare as Sylveon and the other Eeveelutions’ Master Ball Reverse Holo, it is a lot more expensive than the rest simply because of the featured Pokémon, which is more popular than the rest. The card doesn’t have an incredible gameplay value and can be easily taken out, but it’s its rarity and the community’s devotion to Umbreon that makes this Master Ball Reverse Holo the most expensive card inPokémon TCG’sTerastal Festival Exset at a whopping $242, according toPokebeach.
