Singles, Slabs, Sealed and Card Show Chaos
Splash & Shadow TCG started with Ludwig and Renee, two Vegas-based collectors turning a mountain of cards into a real card-show vendor brand.

ShadowWave is a desktop pricing and market-intelligence tool for Pokémon TCG vendors — built by someone running the same inventory you are. Import the collection you already track, price it against live market data, and see which of your cards are moving before the rest of the market does.
Trends in this hobby surface through influencers — after the market already moved. By the time it's a video, you're buying the top and selling the bottom.
A card that books $80 but never sells isn't an $80 card. For a vendor, liquidity matters almost as much as price — and no tool you use today measures it.
You've already built your collection in Collectr, TCGplayer, or Shiny. Retyping thousands of cards to switch tools was never going to happen.
Two parts: the desktop app where you run your collection, and a background service that watches the market for you overnight. Here's what's inside.
Bring the files you already have — Collectr, TCGplayer, and Shiny imports built in, plus plain CSV. The biggest players in the space, no retyping a single card.
Velocity and volume signals on the collection you actually own — flagged before the trend hits your feed. Influencers report the wave. You'll have seen it forming.
Every card gets a concrete liquidity score with the data to back it up — because whether it sells matters almost as much as what it books.
Not just raw-versus-slab. ShadowWave flags US/EU price spreads across your inventory — an edge almost nobody in the hobby is playing.
Export a pre-priced eBay Seller Hub listing file at whatever markup strategy you set. Local data dump means your collection loads instantly — no waiting on the web to refresh.
Every deal you make — bought, sold, or traded across the table — tracked in one place, so you finally know your real numbers.
Most pricing tools give you one number and let you assume it's real. ShadowWave labels every price and liquidity score with where it came from — so you know when you're looking at proof, and when you're looking at an estimate.
"I built ShadowWave because I was tired of pricing my own inventory off gut feel and a browser full of eBay tabs. I'm a vendor first. Every feature in here is something I needed for my own binder before it was something I built for anyone else's."
ShadowWave opens for beta testing soon. Vendors get in first. Drop your details below and you'll hear from us the moment it's ready to install.
Follow for launch newsLudwig and Renee didn't start as vendors. They started as collectors — the kind who obsess over condition, argue about which sets actually matter, and have definitely stayed up too late watching market trends move. Somewhere between a mountain of bulk and their first card show table, Splash & Shadow TCG was born.
Based in Las Vegas, they run a booth that doesn't fit neatly into one box. Pokémon singles, PSA slabs, sealed product, bulk boxes, trade binders, collection buying — if it's in the hobby, it's in the mix. But the real goal has always been bigger than the booth.
Ludwig is building ShadowWave — a next-level analytics platform for collectors and vendors who are serious about the market. Real data, real insights, the kind of tool that didn't exist yet so he decided to build it himself.
On the content side, Splash & Shadow is doing things differently. No boring pack openings. No inside jokes that only vendors get. Instead: something artistic, something that actually captures what makes this hobby feel electric — whether you've been collecting for 20 years or just pulled your first rare.
The bigger plan? Travel. New cities, new shows, new collectors. Because the cards are cool, but the people are the point.
Collectors first. Always.
