Find a good trading partner
It is advantageous, but sometimes challenging, to find an optimal trading partner. A good place to start is with the information provided on the owners page:
"Trader Grade" shows how responsive a trader is to accepting offers
"Owned" reveals you how many copies of this card a trader owns
“Series Completion" tracks how close a trader is to completing the series
Let’s start with Traders Grades. The trading accessibility of each owner is measured by a letter grade A through F. Owners with an A+ trader grade answer every single offer and accept a high volume of trades; Owners with an F trade grade rarely, if ever, respond. Owners with a high trade grade are less likely to allow a trade offer to expire, meaning you will get a response more quickly. Selecting a trade partner with a higher trade grade greatly increases your odds of a having your trade accepted or receiving a counter-offer.
Another great tip is to look at the Owned column to find owners with duplicates of the sought-after card. Traders with duplicates (2x or more) are more likely to part with one of their cards then to break up their collection.
Use the Series Completion percentage to find collectors still actively working to finish the series. Owners with lower series completion percentages may need your help in completing the series and could provide more trade options. But don’t forget owners at 100% completion as they may be more willing to give away duplicates when trading across different series.
Remember, you can toggle any of the above options to reorganize the owners list to fit your specific need. Try different combinations and scroll through the list to search the results.
Use the Message button to communicate with potential trade partners if you have any specific questions about their collection or what they might be looking for in exchange. This is especially useful in discussing hard-to-find out-of-print card trades, in proposing a cross-series exchange, or when offering multiple trades at once.
Make compelling trade offers
Now that you have selected a trade partner, here are some tips to keep in mind to make a successful trade offer:
Offer a fair and balanced trade: When building your trade, you can select up to five cards on each side. You will have the most success when making a fair offer based on rarities and number of cards offered. A Chase for a Chase is a great offer; a Rare and a Common for a Chase is not.
Add a little extra: Looking to swap Very Rare for Very Rare on a series? Throw in that Common or Uncommon they are missing to help seal the deal.
Give them what they want: When constructing your offer, stick to series your trade partner is already collecting. The cards you offer from an unfamiliar series might not be as valuable to your partner as they are to you.
