Collectible Card Game Headquarters

As many of you who play EDH may be familiar with, the popular site EDHREC has a feature where you can see what an average deck looks like based on the statistics it's found from decks online.

In the past I would manually copy and paste these decks in the deck editor importer to try them out. Long story short I got sick of that, scraped the site for all its decks and with a bit of regex and python work I've gotten every average deck (and themes) formatted for Forge.

3691 decks, which includes each theme that may be popular with each commander that EDHREC tries to build average decks with.

Any questions or feedback would be great to hear.

Thanks for that !

I have been really enjoying the decks and was wondering if you could post updated decklist now that M20 and Commander 2019 have been released or if you could post the script you used. Thanks in advance

Thanks!

The program that I used was WinHTTrack Website Copier (http://www.httrack.com). It's something I've had lying around for a while, so I couldn't speak about what other programs or script methods are better than this, but it did the job I wanted.

The address I set the program to copy everything from was https://edhrec.com/decks/ hoping that I'd get just the basic average decks, but luckily I ended up with all the themes for each commander as well.

So I end up with a bunch of html files with the commander and theme in the file name. What I want isolated in each of them is a div with a class labelled "test_cardlistscontainer". This is the div with just the deck, and a couple "buy this deck here" links. The problem is editting thousands of files with the same regex to scrape away all the other html stuff.

I ended up using another program I had called Ecobyte Replace Text (http://www.ecobyte.com/).

I use this to apply regex text replacements across all the files. Once I was done, I then decided to take some time and relearn a bit of python to go through all the files add the tags I need for a Forge commander deck.

The script I used is below. It mentions opening up txt files, which I did with the Bulk Rename Utility (http://www.bulkrenameutility.co.uk), renaming all the files from htm to txt, then after from txt to dck. I'm a Windows user, and while I could be doing a lot of this in linux and bash, windows and batch files, or python if I took the time to learn it better, I would have but I also like collecting these kinds of utility apps and only using them when I need to.

The python script:

Code: Select all

import os

for filename in os.listdir(r"C:\Users\------\Desktop\EDH Rec Average Decks"):
    if filename.endswith(".txt"):
        textfile = os.path.join(r"C:\Users\------\Desktop\EDH Rec Average Decks", filename)

        # Get the file's name without extention
        textnamebase = os.path.basename(textfile)
        name = os.path.splitext(textnamebase)[0]

        print(name)

        newfile = open(os.path.join(r"C:\Users\------\Desktop\EDH Rec Average Decks\New folder", "new"+filename),"w")

        newfile.write("[metadata]\n")
        newfile.write("Name="+name+"\n")
        newfile.write("[Commander]\n")

        with open(textfile,"r") as file:
            file.readline()
            newfile.write(file.readline())
            newfile.write("[Main]\n")

            for line in file:
                newfile.write(line)

        file.close()
        newfile.close()

        continue
    else:
        continue

I wanted to post an update about downloading the decks from EDHREC.

I've made a script in python where when you run it, you'll be asked to enter a legendary creature, and it'll get the average deck and all other themed decks related to that commander. A good place to put this script would be the commander decks folder for Forge, and then run it whenever you want all the current decks on that commander, and it'll drop the deck files right in the same folder.

Code: Select all

import urllib.request
import re
import time
from bs4 import BeautifulSoup

def savedeck(url,partner=False):
    # Get the html of the card's page
    fp = urllib.request.urlopen(url)
    mybytes = fp.read()
    mystr = mybytes.decode("utf8")
    fp.close()

    # Isolate the div with the decklist
    content = BeautifulSoup(mystr, 'html.parser').find("div", class_="well")

    # Remove the first three lines, which are two links to buy the deck and an empty line
    decklist = re.sub('<[^<]+?>', '', content.text).split("\n",3)[3].replace('\n\n', '\n')

    # Turn the deck into a list
    decklist = decklist.split("\n")

    # The name of the deck is just the page's folder name
    name = url[url.rindex('/')+1:]

    # Write the .dck file
    file = open(name+".dck","w")
    file.write("[metadata]\n")
    file.write("Name="+name+"\n")
    file.write("[Commander]\n")
    file.write(decklist[0]+"\n")
    if partner: file.write(decklist[1]+"\n")
    file.write("[Main]\n")
    for i in range(1+partner,len(decklist)):
        file.write(decklist[i]+"\n")
    file.close()

    # Return the html text
    return mystr

def getdecks(url,partner=False):
    # Print the names as you go
    name = url[url.rindex('/')+1:]
    print(name)

    htmltext = savedeck(url,partner=False)
    otherdecks = re.findall(name+'-.*">',htmltext)

    # Repeat for all other themes found
    for i in range(len(otherdecks)):
        # Limits the scraping to two decks a second
        time.sleep(0.5)

        # Trim off the "> from the regex search
        otherdecks[i] = otherdecks[i][:-2].lower()

        print(otherdecks[i])

        savedeck("https://edhrec.com/decks/" + otherdecks[i],partner=False)

card = input("Legendary Creature: ")

# Turn the card into a URL
card = re.sub(" ","-",card)
card = re.sub("'","",card)
card = re.sub(",","",card)
card = re.sub('"',"",card)

getdecks("https://edhrec.com/decks/" + card.lower())


This of course requires Python, as well as BeautifulSoup, which is an HTML parser. You can easily download it (on Windows) by typing "pip install bs4" into the command prompt. A good trick as well if you're interested is shift + right-click in the folder that the script is in, select "Open Command Window here". Then type "py " and drag and drop the .py file to run it in that folder.

You could always modify the code as well to run the code through a loop for each commander name in a list.

Also, as for my description on scaping EDHREC before with WinHTTrack, I forgot that I didn't simply enter "https://edhrec.com/decks/", but a list of all the commanders' deck pages. Otherwise you get a 404.

Finally I'm providing zip files of updated decks and commanders as of Sept 27. 4573 decks in total.

Thank you!

I wanted an updated version of these decks especially with all the commander related products releasing lately and the decks being almost 3 years old. So I modified LtEntropy's Python script to work with the current EDHREC website.

There are 8100 decks included in this download which I had to split into five parts.

Enjoy!

Thanks; Post the updated script please.
