Helps Eternal players evaluate cards based on their frequency of use in decks the user is interested in.

Eternal Card Evaluator takes the user's card collection and a weighted list of EternalWarcry deck searches, and exports an ordered list of cards with the number of relevant decks that have at least one more copy of the card than the user has in their collection. Focusing on buying the cards higher on the list will bring the user closest to building the relevant decks.

Setup

If you're reading this from the Github page, click "Clone or download," "Download ZIP," and extract the archive.

Navigate to the dist folder inside. All interaction with Eternal Card Evaluator must take place in the dist folder. Everything outside of the dist folder can be safely deleted, and is only there to allow viewing and modification of the source code.

Supply your collection

1. In Eternal -> Cards -> My Collection -> press "Export Collection."
2. Paste to collection.txt (the one in dist) to supply your collection data.

Choose the decks you're interested in

Eternal Card Evaluator reads decks from EternalWarcy Deck Searches.

Use the search criteria to make a search for decks that you want to emulate or build.

This is subjective, but some things you may want to look at are:

• Recent tournament decks.
• Decks including cards you want to play around.
• Decks by notable players.

Note that any very large searches, such as "all time" searches, may take a very long time to process, save as a very large file, and even cause out-of-memory crashes. I recommend using 90 days as a maximum.

In the future, additional search parameters may be added, such as filtering by views or rating.

Supply the decks you're interested in

1. Supply any search criteria you want in the EternalWarcy Deck Search interface.
2. Press search. Stay on the first page of the search results (URL cannot have a "p=x" term).
3. Open search_urls.csv
4. Add a line to the file of the form:"Search Name, Weight, Search URL"
5. Repeat from 1. any number of times, to add additional searches.

Search Name is used to label the output for that search. Weight is the proportion that cards from that search will be prioritized. A card used in a search with a weight of 4 will count for twice as much as a card in a search with a weight of 2.

For example Tournament 15, 2.5, https://eternalwarcry.com/decks?td=1&mdb=15 represents all tournament decks in the last 15 days.

Getting your results

Whenever a new set comes out, run "Update_Cards.exe." If this program hasn't been updated in a while, it may be necessary to run the first time you use it. Update_Cards.exe learns from EternalWarcry, so you may have to wait for them to update with the new set.

Whenever you change your deck searches, or want to load in recent changes to the searches, run "Update_Decks.exe." This grabs any new decks in the search, and deletes decks that no longer fit the search. It tries not to redo any work, so it shouldn't take long if it only has to make a small change.

To update your results, run "Generate_Overall_Value.exe." This combines the statistics from the decks, your collection, and the weights you provided for the deck searches, to output a file called "Dist/Output/Overall_Value.json." This information is then used to create evaluate the most efficient ways to spend gold, which are output in "Dist/Output/Purchases.txt"

Interpreting your results.

Overall_Value.json and Overall_Value_By_Shiftstone.json contain a series of blocks representing cards. In Overall_Value.json, cards are sorted by the frequency they're used in your deck searches. In Overall_Value_By_Shiftstone.json, cards are sorted by the exchange rate of crafting shiftstone to the frequency of use in your deck searches.

"Num_Owned" is the number of that card that you currently own.

"Values" is a list of the percentage of decks in your searches that have more copies than you own.

"values": [
    Percentage with 1 more copy than you own,
    Percentage with 2 more copies than you own,
    Percentage with 3 more copies than you own,
    Percentage with 4 more copies than you own,
]

That percentage is calculated for each of your deck searches, and then averaged together based on the weights you gave. For example, if a card was used in every deck in a search with priority 10, and never used in a search with priority 1, the value would be 90.

Here is some example data for a user with an empty collection, looking to build tournament decks:

[
    {
        "card_name": "Torch",
        "new_count": 1,
        "rarity": "common",
        "value": 47.55012814714307
    },
    {
        "card_name": "Vanquish",
        "new_count": 1,
        "rarity": "uncommon",
        "value": 34.19267299864315
    },
    {
        "card_name": "Seek Power",
        "new_count": 1,
        "rarity": "common",
        "value": 34.132368460726674
    }, ...

The Future

I hope to add:

• Automatically handling updates, rather than making the user click multiple exes.
• Additional search parameters, such as by rating or views.

All of these are somewhat difficult, and may not happen.

Bugs

I hope not.

Please first make sure instructions were followed:

• Only use contents of dist folder.
• Correctly format search_urls.csv
• Make sure cards and decks have been updated before clicking generate_overall_value.exe

Send me the crash dialogue. If the window is immediately closing, make a bat file with the contents

start <exe that's not working>
pause

and run that. That should store the output.

If there is no output, be careful that you aren't missing search_urls, decks or cards.
