The C3 Market page aggregates 7-day price movement across all 8 TCGs covered on this site. It shows which cards are rising, which are falling, and what the current AUD prices are: all on one screen without needing to check each game separately.
This guide explains what each section shows and how to use it to make better buying and selling decisions.
Quick Answer
Go to /market for a quick scan of which cards are moving across MTG, Pokemon, Lorcana, One Piece, Yu-Gi-Oh, Dragon Ball Super, Star Wars Unlimited, and Riftbound. Filter by game to narrow down. Use it before buying expensive singles to check whether the market is moving in a direction that affects your timing.
What the Market Page Displays
Price Movement Indicators
Each card listed on the Market page shows:
Current AUD price: The most recent eBay AU sold price for near mint copies of that card.
7-day change: The percentage price movement over the past seven days. A green positive percentage means the card has risen in price. A red negative percentage means it has fallen.
Trend direction: A visual indicator showing whether the card is on an upward or downward trajectory.
Why 7 Days
Seven days is the standard window for identifying meaningful price movement without noise. A single high eBay sale on one day can distort shorter windows. A 30-day window is too long to catch recent spikes.
Seven days catches: tournament result spikes, reprint announcement crashes, content creator mentions, and ban or unban effects: all of which typically show clear directional movement within a week.
How to Read the Market Data
Interpreting a Rising Card
A card showing +30% or more over 7 days is experiencing a spike. Common causes:
Tournament results: A deck using this card placed well at a major event. Other players are now buying the card to build the deck.
Content creator attention: A YouTuber or streamer featured the card in a video. Short-term demand spike, often corrects within 2 to 4 weeks.
Set announcement: The card was announced in an upcoming set: either as a reprint (price drops) or as something that synergises with a newly previewed card (price rises).
Ban or unban: A card being unbanned in a format creates sudden demand. A card being banned collapses in price.
What to do: if the spike is driven by real tournament performance rather than speculation, the price may stabilise at the new level rather than correcting. If the spike looks speculative (no clear competitive reason), wait for correction before buying.
Interpreting a Falling Card
A card showing -20% or more over 7 days is declining. Common causes:
Reprint announced: Reprints flood the market with new supply, crashing singles prices for the reprinted card.
Meta shift: The card was heavily played in a competitive format, but a ban, new card, or format shift has made the deck weaker.
Hype correction: The card spiked on speculation and is returning to realistic value as buyers realise the theory doesn't work in practice.
What to do: falling cards that have been correcting for multiple weeks represent potential buying opportunities if you believe the card has long-term Commander or collector demand. Don't catch a falling card during an active meta rotation.
Filtering by Game
The Market page lets you filter to specific TCGs. Use this when you only want to see movement in one game rather than scanning all eight.
When to use the full view: Before any major purchase over AU$50 across any game, check the full market to see if there's movement you hadn't noticed.
When to filter: If you exclusively play MTG Commander and don't need Pokemon or Lorcana data, filter to MTG and save time.
The Market Page vs the Compare Tool
The Market page and the C3 Card Compare tool serve different purposes:
Market page: Broad scan. "What is moving right now across TCGs?" Use Market when you don't have a specific card in mind but want to find opportunities or risks.
Compare tool: Specific analysis. "I know the two cards I'm choosing between: show me the price comparison." Use Compare when you have already identified which cards you want to evaluate.
A typical workflow: scan the Market page, identify a card moving significantly, then open it in the Compare tool for a detailed price and trend look before deciding whether to act.
Practical Use Cases
Before Opening a Booster Box
Check the Market page for cards in that set before opening. If three of the top ten cards in a set are falling week-over-week, the set's overall EV is declining. That affects whether opening boxes versus buying singles is worthwhile right now.
Combine this with the C3 EV Calculator for the full picture.
Before Selling Cards You Own
If a card you own is showing strong upward momentum on the Market page, selling now means you are selling into strength. If it's falling, you may want to wait for the movement to reverse: or accept current prices if you need to sell quickly.
After Major Tournament Results
The Monday after a major tournament, check the Market page filtered to the relevant game. Cards from winning decks will show clear upward movement. This helps you understand which cards the community is valuing and whether your existing collection benefits.
Connecting Market Data to Other C3 Tools
C3 Card Vault: Find detailed price history for any specific card. The Market page gives you the overview; the Vault gives the details.
C3 Card Compare tool: Once you identify a card worth investigating from the Market page, use Compare to check it against an alternative.
C3 EV Calculator: Use Market data to understand whether sealed product is becoming better or worse value before running an EV calculation.
The C3 Take
The decisions you make with your TCG collection matter more than most guides suggest. Whether you are buying, selling, or holding, the difference between a good outcome and a poor one almost always comes down to checking current AUD prices before you act. Use the live data at /cards/mtg to make price-informed decisions every time.

Frequently Asked Questions
Is the C3 Market page free to use?
Yes. No account or login required.
How often does the Market page update?
Price data updates regularly from eBay AU sold listings. Significant spikes within the last 12 hours may not yet be reflected.
Does the Market page cover all cards or just the most popular ones?
The Market page focuses on cards with enough sales activity to generate meaningful 7-day trend data. Very low-volume cards or obscure printings may not appear even if their price has moved.
Can I use the Market page to find undervalued cards?
Yes, with caution. Cards showing downward trends that appear to be over-correcting relative to their long-term Commander or collector demand are worth investigating. Use the Compare tool to check historical pricing context before making assumptions about what counts as undervalued.
