Having the average CMC for a deck would be a useful stat for deckbuilding in EDH. I imagine its a quick add too.

    // Initialize array and hash to hold mana costs
    var manaCosts = {};
    var totalCosts = [];

    // Iterate through rows to get mana cost totals for each card
    var x = document.getElementsByClassName("mtg_mana");

    for (i = 0; i < x.length; i++) {
        var re = /mtg_mana_[0-9URGBWCX]{1,2}/i;
        //console.log("This is a mana cost item: " + x[i].outerHTML);
        var row = x[i].parentElement.parentElement.id;

We can accomplish this with a greasemonkey script. My JS skills are garbage but I will work on this a little bit. Any coders out there that want to help, please do.

Like I said: garbage. But it's starting to work.

Limitations: Dies for "X" cards, doesn't ignore sideboard or scratchpad, maybe dies for 0 colorless cards??

Fixed so it only calculates the main portion of the deck and ignores sideboard and scratchpad. Yes, this could be a lot cleaner, and if people want to use it I will clean it up further and make the value display a little sexier (right now it's just a red text box in the top left; not pretty but it gets the job done.)

This will work with tampermonkey too I assume? I am reading into it now, its a new extension for me, but the functionality is worth a bit of a learning curve.

Yeah this is working for me with tampermonkey.

Awesome, thanks.

If you notice it bugging out or not working or seeming to give inaccurate results please let me know and I'll try to fix. The whole thing is a quick and dirty hack job, but it seems to work for now.

Its better than not having it, so it works for me. Thanks again.

Just a quick update for anyone else looking to use it.

Works perfectly for me so far, no issues.

Thanks again!

Found a bug:

Doesn't work for this deck: https://deckbox.org/sets/1603743

Not sure why, box just doesn't show up.

Ah OK it's almost certainly because of the colorless mana.

I will put a fix up in a few minutes.

Fixed:
1. Was incorrectly parsing two digit numbers. The script now does a replace on the mana element name rather than simply stripping to the last character.
2. Was not set up to handle colorless mana.

Working well, thanks!

Perhaps you could update your initial post with a copy of the script so people who find this thread can easily get access to it?

I also wonder if I should create a separate post somewhere on this forum to bring it to peoples attention.

A new post would probably be best. It should definitely be advertised, its such a useful feature. I can update my initial post as well, what do you use to inlay the code in the scroll-able box like that?

Another bug: https://deckbox.org/sets/1043553

Returns "NaN".


Possibly from the commander having so many mana symbols? Not sure.


Edit: Same thing for these decks:

Unsure what the common denominator is, they all worked before.

They all have at least one card whose cost contains hybrid mana. Maybe that's the issue?

Yes, this is the issue. Before, we were simply trimming to the last character to identify a mana cost, but in one of the updates I found that this was broken for double digit mana costs. To fix that, we started trimming the mana element to a more precise name, which meant that these dual mana costs (RW, UW, RB, etc) weren't being handled correctly.

It is fixed in the update below.

In fixing that bug I think I have found another problem with the script: I believe it only truly works for EDH decks because it doesn't take into account the NUMBER of each card in the deck. What I mean is that you have more than one of a single card in a deck, the script does not take that into account in calculating the CMC average. What is displayed is the CMC average for all UNIQUE cards in the deck, meaning that the second, third, and fourth instances of a card will not affect the calculated CMC. I'm new to magic and unsure if this is desired, or if when calculating CMC average, multiples should be taken into consideration. Let me know and I will update the script if that shouldn't be the case.

Here is the fixed script to account for the hybrid mana symbols:

Ok, 0.5.1 fixes some of the debug logging for the JS console and prepares me to fix the issue mentioned above. Functionally the same as 0.5.0 but better output in console.

Here's example console output for one of the decks you posted above (https://deckbox.org/sets/847100)

This should make it a lot easier to tell if mana is being calculated correctly, and will aide me in accounting for multiple instances of cards within a deck.

The only time you will see this is for shadowborn or relentless decks where you can play any number of that card.

It worked on all the singleton decks I tested.

Works for the 20 or so decks I tested. Awesome work. Sebi should just add this to deckbox's code.

Awesome. Can you edit your first post to include that version of the script. Use the code button above the post edit box () to format the code correctly.

Done.

I need to make a fix here for Phyrexian mana. Will do so this weekend.

Wasn't working for me so I tinkered with it to get it to work. Also moved the popup so it doesn't hide the "Home" button anymore :)

I was going to make a new post a request for Automatic CMC but seems that we've got some interest here. So ditto for me on implementing something like this so I don't have to count symbols manually.
