serra

Serra is my personal Magic: The Gathering collection tracker.

It began as a holiday project in winter 2021/2022 because I was frustrated of Collection Tracker Websites that are:

Pain to use
Want ~$10 a month
Don't have the features I want

So I started my own Collection Tracker using Golang, MongoDB and Scryfall to have an overview in what cards you own and what value they have.

What Serra does

Tracks prices
Calculates statistics
Query/filter all of your cards
Shows what cards/sets do best in value development.

What Serra does not

Does not give a shit about conditions (NM, M, GD...)

Quickstart

Install Binaries

on macOS you can use

brew install noqqe/tap/serra

on Linux/BSD/Windows you can download binaries from

https://github.com/noqqe/serra/releases

Spin up Database

To run serra, a MongoDB Database is required. The best way is to setup one by yourself. Any way it connects is fine.

You can also use the docker-compose setup included in this Repo:

docker-compose up -d

Configure the Database

Configure serra via Environment variables

export MONGODB_URI='mongodb://root:root@localhost:27017'
export SERRA_CURRENCY=USD # or EUR

After that, you can add a card

./serra add usg/17
./serra update

Start exploring :) (the more cards you add, the more fun it is)

Usage

The overall usage is described in --help text. But below are some examples.

Usage:
  serra [command]

  add         Add a card to your collection
  card        Search & show cards from your collection

  help        Help about any command
  missing     Display missing cards from a set
  remove      Remove a card from your collection
  set         Search & show sets from your collection
  stats       Shows statistics of the collection
  tops        What cards gained most value
  update      Update card values from scryfall
  web         Startup web interface

Flags:
  -h, --help      help for serra
  -v, --version   version for serra

Use "serra [command] --help" for more information about a command.

Add

To add a card to your collection.

Cards

Query all of your cards with filters

Sets

List all your sets

Set

Show details of a single set

Stats

Calculate some stats for all of your cards

Tops

Show what cards/set gained most value

Flops

Show what cards/set lost most value

Update

The update mechanism iterates over each card in your collection and fetches its price. After all cards you own in a set are updated, the set value will update. After all Sets are updated, the whole collection value is updated.

Adding all those cards, manually?

Yes. While there are serveral OCR/Photo Scanners for mtg cards, I found they are not accurate enough. They guess Editions wrong, they have problems with blue/black cards and so on.

I add my cards the add --interactive feature, since they are sorted by editions anyways.

> ./serra add --interactive --unique --set one
one> 1
1x "Against All Odds" (uncommon, 0.06 USD) added to Collection.
one> 1
Not adding "Against All Odds" (uncommon, 0.06 USD) to Collection because it already exists.
one> 3
1x "Apostle of Invasion" (uncommon, 0.03 USD) added to Collection.

Its basically typing 2-3 digit numbers and hitting enter. I was way faster with this approach then Smartphone scanners.

Development

Install

go build .
./serra

MongoDB Operations

A few commands that do backups and exports of your data inside of the docker container.

Do a database dump

mongodump  -u root -p root --authenticationDatabase admin -d serra -o /backup/

Do a collection export to json

mongoexport  -u root -p root --authenticationDatabase admin -d serra -c cards > /backup/cards.json
mongoexport  -u root -p root --authenticationDatabase admin -d serra -c sets > /backup/sets.json
mongoexport  -u root -p root --authenticationDatabase admin -d serra -c total > /backup/total.json
