Once you see Pikachu, you cannot unsee it
Bulbasaur 037 already looked like the kind of promo collectors would eventually circle back to. Bright art, clean framing, a starter Pokemon, and enough little details to make the card feel bigger than a normal promo. Then people noticed the Pikachu tucked into the scene, and now the card has a story.
That is the whole game with collector cards. Rarity matters, but a good story travels faster. The Pikachu detail is small enough to feel like a discovery and obvious enough that once someone points it out, everyone wants to check their copy.
And because the card is tied to Mega Evolution Promos and the 2026 anniversary-era product push, the timing is perfect. People are already looking harder at promos. This gave them a reason to look at Bulbasaur first.
Bulbasaur 037 is a Mega Evolution Promos card released March 20, 2026.

Why tiny art details move real money
Hidden or easy-to-miss art details hit collectors differently than a normal rarity stamp. They make the card feel like it rewards attention. That matters because collectors do not just buy cardboard. They buy the story they can tell about the cardboard.
With Bulbasaur 037, the Pikachu in the scene gives the card a little Red and Blue energy. It feels like a Viridian Forest wink, which is exactly the kind of thing older Pokemon fans love. It is not just cute art anymore. It is a card people want to show someone else.
That does not mean every copy should suddenly be priceless. It means the card has a stronger floor than it did before people noticed the detail.

The price move is already loud
The live market has already moved into the roughly $50 range, with some listings and comps pushing higher depending on condition and timing. That is a big jump for a promo that a lot of people were treating like a quiet binder card a few weeks ago.
I would be careful chasing the first spike. Cards like this usually get a quick discovery pump, then a small fade as people list extra copies, then a slower climb if the collector story keeps spreading.
That fade is where I would rather buy. Chasing the first loud week is how you end up paying the content price instead of the card price.

The rest of the promo line deserves a look too
The bigger signal is that people are going to start checking the rest of the promo line harder. That is usually what happens after one hidden-detail card pops. Collectors start zooming into every background, every reflection, every little object, looking for the next thing.
That does not mean every starter promo is about to moon. But it does mean the whole group gets more attention, and attention is usually the first step before price movement.
If you already have related promos sitting in a binder, I would pull them out and actually look at the art. Not just the rarity. The art is the thing doing the work here.
What I would actually do
If I already owned Bulbasaur 037, I would keep it. The Pikachu detail is not going away, and this is exactly the kind of promo people remember later.
If I wanted to buy one now, I would not chase the highest current listing. I would set an alert below the spike and wait for the first wave of flippers to undercut each other.
And if you are watching the market, the lesson is bigger than one Bulbasaur. Promo cards with real art stories can move faster than people expect. The trick is finding them before everyone else zooms in.
