Introduction
CardMind is a market intelligence platform for Magic: The Gathering collectors. It is not a store, not a price guide, and not a deck-building calculator in the traditional sense. It is a data platform that tracks what is happening across the MTG market and surfaces the signals you need to make informed decisions about your collection.
If you have ever refreshed a buylist page wondering whether a card has already spiked, or found out two days late that a card you owned hit $80 because of a tournament, CardMind is built for you.
The problem we solve
Most MTG collectors manage prices the same way: a spreadsheet updated manually, a Reddit thread bookmarked from six months ago, and a Discord server that moves too fast to follow. Signal information — the kind that actually matters, like a card spiking because of a tournament result or a buylist drop ahead of a ban announcement — is scattered across a dozen sources and arrives hours or days after the movement has already happened.
There has never been a single place that connects live price data, signal detection, and collection tracking for MTG. CardMind is that place.
What you see on the homepage
The CardMind homepage is a live market overview. You do not need an account to view it. Here is what each section shows:
Live price ticker
At the top of the page, a scrolling ticker displays cards with notable recent price changes. Each entry shows the card name, its current market price, and the 24-hour percentage change. Green entries are rising; red entries are falling.
Top 100 most valuable cards
The Top 100 section lists the most valuable Magic cards on the market right now, ranked by Scryfall market price (which mirrors TCGPlayer market data). Each row includes a 7-day sparkline so you can see the price trend at a glance without clicking into anything.
Price movers
Below the Top 100 sits the Movers section: the biggest 24-hour risers and fallers across the entire MTG card catalog. This is where you will see cards that have spiked due to tournament results, viral social posts, or buylist changes — usually within hours of the movement beginning.
Signal detection
Signals are the core of CardMind. The platform monitors price history, buylist changes, tournament results, and ban announcement patterns across the entire card catalog. When something meaningful is detected, a signal fires.
Signal types include:
- Price spike / price drop— Sudden movement above or below a card's 90-day average
- Buylist rise / buylist drop — Card Kingdom buylist changes that signal dealer sentiment
- Tournament dominance / emerging — Cards showing up heavily in recent tournament top 8s
- Ban window — Cards matching historical patterns that preceded ban announcements
- Buy opportunity — Cards trading significantly below their 90-day average
- Volume spike — Unusual transaction volume suggesting market activity
Every signal shows a confidence level — HIGH, MEDIUM, or LOW — based on how strongly the card matches the detection criteria. CardMind publishes a monthly accuracy track record so you can evaluate signal quality over time.
Free tools anyone can use
Two tools on CardMind require no account at all:
Collection calculator
Paste a card list, add cards by name, or upload a CSV export from Moxfield or Deckbox. The calculator applies condition multipliers automatically (NM is baseline; LP, MP, HP, and Damaged each reduce value proportionally) and shows you a total market valuation in seconds. See the collection calculator guide for a full walkthrough.
Deck Intelligence
Paste any MTG decklist in MTGO, MTG Arena, Moxfield, or Deckbox format. CardMind parses the list, matches the cheapest available printing for each card, and shows you a live total cost breakdown. Add a commander name to unlock EDHREC recommendations for your deck. See the Deck Intelligence guide for details.
All price data on CardMind is also free to browse — card detail pages, price history charts, and the Top 100 are accessible to everyone.
Plans and pricing
CardMind has two paid plans beyond the base experience:
- Player — Unlimited AI card analysis, email price alerts, and a daily portfolio briefing. For collectors who want to stay ahead of the market on the cards they own.
