If you’re new to collecting Pokémon cards, chances are that Squirtle will be one of the first Pokémon you encounter. This water-type starter from generation one has been beloved since the beginning, and its evolution line Wartortle and Blastoise have firmly established themselves in every collector’s heart. In this blog, I’ll tell you why this classic line is still so popular and which cards you should really 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. It was a reliable choice in the games, and that reputation carried over into the TCG. Its evolution into Wartortle adds a tough edge, and eventually it transforms into Blastoise, a tank of a Pokémon with water cannons on its back.

Blastoise was one of the strongest cards in the Base Set right away, and he continues to impress to this day. His cards are often strategically strong and visually iconic. Especially the holofoil Base Set Blastoise is a must-have for vintage collectors.

Why are Squirtle cards so popular?

For many, Squirtle represents the beginning of their Pokémon journey. The combination of recognizability, nostalgia and powerful evolution makes his cards extra attractive. His cards are also often released with fun or artistic designs, which makes them popular with both collectors and players.

However, it's not just nostalgia. Blastoise has had many strong cards over the years, think Blastoise EX, Blastoise GX and Blastoise VMAX. These cards have not only become playable, but also collectibles.

My experience with Squirtle and evolutions

I remember vividly when I was a kid, drawing my first Blastoise. It wasn’t Charizard , but it felt like it. The shine, the power, the weight of that card, it triggered something. To this day, that feeling hasn’t changed. Every time I see a Squirtle card, that bit of nostalgia comes flooding back.

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

So keep an eye out for new releases, because Blastoise pops up more often than you think and each new card could easily become the next classic.
