If you are only just starting to collect Pokémon cards, there is a good chance that Squirtle is one of the first Pokémon you come across. This Water-type starter from the first generation has been loved since the very beginning, and its evolution line – Wartortle and Blastoise – has won a permanent place in the heart of every collector. In this blog we tell you why this classic line is still so popular and which cards you really need to keep an eye on.

The evolution of Squirtle

As you know, it all starts with Squirtle. This little turtle Pokémon is not only cute, but also surprisingly powerful. In the games it was a reliable choice, and that reputation carried over into the TCG. Its evolution into Wartortle adds a tougher edge, and in the end it transforms into Blastoise – a tank of a Pokémon with water cannons on its back.

In the Base Set Blastoise was one of the strongest cards straight away, and it still impresses today. Its cards are often strategically strong and visually iconic. The holofoil Base Set Blastoise in particular is a must-have for vintage collectors.

Why are Squirtle cards so well loved?

For many people Squirtle represents the beginning of their Pokémon journey. The combination of recognisability, nostalgia and that powerful evolution makes its cards extra attractive. Its cards are also often released with fun or artistic designs, which makes them popular with collectors and players alike.

That said, it is not only nostalgia. Blastoise has had plenty of strong cards over the years – think of Blastoise EX, Blastoise GX and Blastoise VMAX. Those cards are not just playable, they have become collector's items too.

The most popular and most expensive Squirtle evolution cards

These cards stand out – in value as well as in popularity:

Blastoise (1st Edition & Shadowless) – €624 – €30,125 (PSA 10)
Blastoise EX (XY Evolutions) – €49 – €319 (PSA 10)
Blastoise GX (Unbroken Bonds) – €79 – €251 (PSA 10)
Blastoise VMAX (Sword & Shield Promo) – €19 – €251 (PSA 10)
Squirtle (Team Magma & Team Aqua Pokemon Cards) – €55 – €1,533 (PSA 10)

As you can see, it is not only the Blastoise cards that are worth money. Certain Squirtle releases have become surprisingly rare too.

Our experience with Squirtle and its evolutions

We still remember pulling our first Blastoise as a kid. It was not a Charizard, but it felt like one. The shine, the power, the weight of that card – it did something to you. To this day that feeling has not changed. Every time we see a Squirtle card, that bit of nostalgia comes right back.

Squirtle and its evolutions are a safe and a smart choice for any collector. They combine play value, historical meaning and consistent popularity. Whether you are only just starting out or have been collecting for years, there is always room for these water powerhouses in your collection.

So keep an eye on new releases, because Blastoise turns up more often than you think – and every new card could easily become the next classic.
