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.
Fast Movers and a Sleeper Watch 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 plain-language liquidity read — Illiquid, Slow But Movable, Medium, and beyond — right next to the price. Because whether it sells matters almost as much as what it books.
See the real return on sending a raw card to PSA — gem rate, fees, and payout net of costs, right in the Vault. Country-to-country price gaps are next on the roadmap.
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.
No mockups. Every screen below is the live app, mid-beta, running real inventory.
$5,454.92 in expected profit across current holdings — per card, with gem odds pulled from real pop-report data, fees, and expected sale price after costs. Not a guess.
Cost paid, live price, liquidity tier, and raw-to-slab ROI — side by side for every card in the Vault, updated on every pricing run.
PSA, BGS, CGC — every grader, tracked and priced right alongside your raw singles and sealed product. Same Vault, no separate spreadsheet.
Collectr, TCGplayer, Shiny, or a plain CSV — drop it in and ShadowWave takes it from there. No retyping a single card.
Batch-select cards in the Vault and export a ready-to-upload eBay CSV in one click — no re-keying prices into Seller Hub.
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.

Pricing and market intelligence for your whole collection. Import what you already track, price it against live market data, and see which of your cards are moving before the rest of the market does.
Take a lookTurn the collection you already track into printed price labels. Card name, your logo, and a QR code back to your shop, sent straight to the label printer on your table.
Take a lookShadowTag is an iPhone app that turns the collection you already track into printed price labels: card name, your logo, and a QR code back to your shop, sent straight to the label printer on your table. Your prices come from your file, never from the internet.
First the lookup, then the negotiation. Every card without a price on it is a question you have to stop and answer, and a number you end up defending on the spot.
Price a card too high and the customer never even asks. Price it too low and you just sold yourself short. The number you worked out at home is the right one. It needs to be on the card.
Most of your box is priced the same as it was last weekend. Reprinting all of it is a wasted roll and a wasted evening. You only need the ones that changed.
ShadowTag does not try to be your inventory system, because you already have one. It does the last ten feet: getting the price you already decided on onto the card in front of the customer.
TCGplayer, Collectr, Shiny, and ShadowWave exports all import directly. Tap Import in the app, or share a CSV to ShadowTag from Mail or Files. Nothing to retype.
Set your price bands once: exact under $30, ending in 9 through $95, odd dollars above $100. Every label follows the rule, so a $185.60 card prints as $187 without you touching it.
Every card is New, Changed, or Printed. Import a fresh export before your next show and only the movers come back to the top. Print those, leave the rest alone.
A QR code to your shop or Instagram, your logo, the card name, and the price, laid out live at true printer resolution so what you see is what comes off the roll.
Pair over Bluetooth, watch the signal strength, print a test label before you commit a roll. It reconnects to the same printer when you get to the venue.
Select what you need, see how long the run will take before you start it, and let it go. Forty labels is about forty seconds.
Just a vendor helping other vendors. No subscription, no account, no trial that quietly ends, and no upsell three screens in. Buy yourself a printer for under $30, load whatever labels you like, and that is it.
The subscription is the part you can walk away from. The printer and the label supply are the part you cannot. On their monthly plan that is $612 a year before you buy a single roll, and every roll after that has to come from them.
Every screen below is the finished app running a real collection.
Export from whatever you already run your inventory in and ShadowTag reads it. The prices on your labels are the prices in your file, full stop.
Decide once how each tier should round and the whole collection follows. Cheap cards stay exact, mid cards end in 9, expensive cards land on odd dollars.
New, Changed, and Printed are filters, not decoration. Import a fresh export and the app tells you exactly which cards need a new label, then prints only those.
Scan, tap your printer, print a test label. Signal strength is right there, so you know before the doors open whether the printer will hold the connection from under the table.
Pricing tools that phone home end up deciding your prices for you. ShadowTag never does. The number on the label is the number you imported, and nothing about your inventory leaves the device.
"I built ShadowTag after spending a night up till 3am pricing every card in my inventory. Only to find myself at the table the next day, STILL writing those prices on sleeves with a Sharpie. 😭 The work was already done. The prices just hadn't made it onto the cards.
It's free because I'm a vendor first, and this is the tool I wanted somebody to hand me."
ShadowTag is free, the way it will always be. Access codes go out by hand, so follow Splash & Shadow on Instagram and send me a DM. I'll get you a code.
Ludwig 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.
