About CardActivity

Building trust in a market known for shady practices
CardActivity started with a simple idea: Pokémon fans love mystery boxes, but they hate getting ripped off.
So they made physical mystery boxes that were actually fair. They focused on quality products and honest dealings. It worked. They’ve got a 4.8-star rating from over 150 reviews, which is pretty rare for mystery packs.
“That level of trust is pretty unheard of for Mystery Pack products.”
The challenge: Keeping up with the market demands as they scale

The Pokémon card market kept changing, and CardActivity needed to evolve.
They want to digitalize their store and offer virtual mystery boxes, but not just any digital experience. They needed something that could handle their complex product structure while keeping the transparency their customers loved.
The requirements were clear:
Keep up with what the market was demanding
Move to digital mystery boxes with full transparency on items and winning odds.
Do it fast without the cost and hassle of building everything from scratch
The solution: Mysbox handled the complexity, so they didn’t have to

They went with Mysbox. CardActivity’s setup isn’t simple. They run three main product categories (sealed products, raw/single cards, and graded cards), each with six different price tiers.
That’s a lot of inventory to manage, and a lot of odds to calculate.
Mysbox handled it all:
Automatic odds calculation.
CardActivity just adds their inventory, sets the parameters, and Mysbox handles the math. Every customer sees accurate odds for every item they might pull.
Instant gratification.
No more waiting for shipping. Customers open their mystery boxes instantly on the website and see their pulls right away.
Built-in transparency.
Every mystery box shows potential items and their pull chances before purchase. Customers can browse what's possible, check the odds, and decide if it's worth it.
Responsive support when it mattered.
Even without every feature in place, the Mysbox team partnered with CardActivity to find workarounds, support custom needs, and resolve issues quickly—making a fast launch possible.
“I like Mysbox because of the quick support and the team seems to be ramping up very quickly.”
Results: Early traction before the official launch

They haven’t even done a full launch yet, but things are looking good. Just from posting on Instagram Stories:
Conversion rates went up
Customers can see what they might pull before buying, which builds trust
Their community is engaged and excited
“People got to see the hits before buying, which is perfect.”
What’s next: Shaping the future of Mysbox together
One thing CardActivity values most? Being heard. They worked closely with the Mysbox team, sharing feedback that actually shapes what gets built next. It’s not just about using the app, it’s about helping build it.
CardActivity keeps giving Mysbox feedback on what would make things better:
Cooler opening experiences (backgrounds, animations, sounds)
Show what people are pulling in real-time
Let customers resell their pulls
Better ways to organize prizes in boxes
Customer inventory system with flexible shipping
Buyback options (already being worked on)
Leaderboards to reward active customers
“I’m very happy with the team’s support to get things done quickly.”
