Collecting Pokémon cards has seen a massive comeback in recent years. For some, it's a trip down memory lane; for others, it's a way to de-stress, and for some, it's a form of investment. Ultimately, the most important thing is that you enjoy it. That moment when you open a pack and for a few seconds have no idea what you're going to pull is exactly why people keep coming back.
Pokémon TCG operates on a system of sets released throughout the year. Each set has its own unique cards and a limited print run. Once printing stops, availability gradually drops, and some cards and products start to rise in value. That's why it's not just the cards themselves that make for a good investment, but the sealed products as well.
Among the most popular are booster boxes and Elite Trainer Boxes.

Pokémon Boxes – Why Not Just Stick to a Few Boosters?
A booster box usually contains 36 packs, making it the ideal choice for those who want to maximize their chances of pulling interesting cards. Plus, opening a box is an experience in itself. You go through one pack after another, and the tension builds with every card.
Elite Trainer Boxes (ETBs) are a popular mix of collectible and practical items. Besides booster packs, they include accessories like card sleeves, dice, or deck boxes, plus a booklet with an overview of the entire set. This is great for beginners because they can immediately see which cards they might find. Thanks to their design, Elite Trainer Boxes often end up as display pieces in a collection.
Beyond that, there are plenty of other products, such as various collection boxes with promo cards, tin boxes, or special editions focused on specific Pokémon. Each of these products has its own charm and targets a slightly different type of collector. Some want to hunt for cards efficiently, while others just want to treat themselves to a nice box they might not even open.

Price trends for individual sets are heavily tied to which Pokémon appear in them. If a set features heavy hitters like Charizard, Pikachu, Mewtwo, Gengar, or Dragonite, it usually generates much more hype and performs better on the market long-term. Fans love these Pokémon across generations, so demand for cards from such sets tends to be higher. You can see this clearly right now with the Ascended Heroes set, which features several of these popular Pokémon, and the prices and community interest reflect that.

How to Identify Rare Pokémon Cards
Cards have several levels of rarity. The base consists of common, uncommon, and rare, but what collectors are really after are the higher rarities. In modern sets, you'll often encounter EX-type cards, which have high gameplay power, and especially IR (Illustration Rare) and SIR (Special Illustration Rare) cards. You can identify these cards by the symbols at the bottom, which determine their rarity.
Basic orientation works like this: a circle denotes a common card, one diamond an uncommon, and one star a classic rare or better. At higher rarities, things get more interesting: two black stars denote so-called Double Rare, which are typically EX cards. Two white stars signify Ultra Rare, which have more striking designs and often texture. Even more interesting are the gold stars, which signal the most attractive pieces for collectors. One gold star is usually associated with Illustration Rare (IR), cards with unique full-art illustrations. Two gold stars denote Special Illustration Rare (SIR), which are even more detailed and visually striking. The absolute peak is three gold stars, which are Hyper Rare cards, characterized by a distinct gold design and ranking among the rarest cards in the entire set.
Cards like IR and SIR are hugely popular today because they feature unique full-art illustrations and feel more like small works of art than just game pieces. And these are exactly the cards that keep people opening packs again and again.
Card Grading
Once you pull an interesting card, the next step is often grading. This means you send the card to a specialized company that evaluates it based on its condition. The most famous is PSA (Professional Sports Authenticator), which grades cards on a scale from 1 to 10. The most sought-after is, of course, a PSA 10, which is practically perfect condition, and such a card can be worth many times more than an ungraded one.
Several factors go into the final grade:
- Centering is very important, meaning whether the borders around the image are even.
- Corners are checked; they must not be bent or worn.
- The surface of the card must be free of scratches and so-called whitening, which are white scuffs on the edges or the back of the card. Even a small detail can decide whether a card ends up as a PSA 9 or the dream 10.
However, it's important to say that collecting Pokémon cards shouldn't just be about investment. Yes, there are cases where people have made good money, and yes, some products or cards grow in value over time. But if you go into it only with the vision of profit, you'll hit a wall very quickly. Most packs won't bring huge collectible value. If you don't enjoy the process itself, the joy of opening packs, and building a collection, you won't last long.
And that's exactly how we approached it. We are two brothers who returned to collecting after years. But this time, we wanted to take it to the next level, combine business with pleasure, and share it with other Pokémon fans. That's how our YouTube channel Dvě vajca was born.

We open packs and boxes, try out different sets, and most importantly, we keep it real, with no pretense. We rely on a relaxed atmosphere, authentic reactions, and real-time emotions. When we pull a banger, we celebrate. When it's a dud, we say it straight. And since we're from Ostrava, sometimes those emotions come out a bit more sharply than a textbook on good manners would allow.
We don't want to play pretend. Pokémon cards are our fun, our way to unwind, and a way to be part of a community that shares the same passion. And if we entertain someone or motivate them to dust off their old collection, even better. If all this sounds appealing to you, you know where to find us.
