This was a suggestion in the feedback survey, and it seems like it'd actually be pretty easy.

Notes to self:

Instructions on how to import from web. Example XML cardset list. It appears to need card spoilers formatted like this, but I can probably arrange for that.

i've yet to install cockatrice. how well does this integration work? can you draft? can you add sets to formats like standard, modern, etc?

I would prefer Lackey. It works on macs, so I can actually use it. Obviously, I understand if it's too much work.

I've at least used Lackey (as of a week ago), so the Lackey option seems fairly plausible. Big problem is that I think it needs card images rendering, and so far I've relied on browsers to do the HTML+CSS rendering of my mockups - I don't have any way to do them server-side.

There are tools for that (headless browsers that render to images). There's even webservices for it nowadays.

Ooh, I'd love to find such a thing, but my Googling so far has failed. Do you have any links?

htmlconverter.org, html2png, phantomjs, crowbar, selenium...

Huh, nothing as turn-key as I thought. I had a really nice webkit-based one that you could drive programatically, injecting javascript, clicking buttons etc. But ti ooesn't seem to be maintained any more. I'll see if I can dig out the code I had.

I've always been a fan of OCTGN, but recent changes have made it even more difficult, if not impossible, to play with custom cards on it.

for custom sets to work in lackey, you have to append the cards to the main file.

I don't believe that's the case. The Goblin Artisans playtest of their Tesla custom set I did doesn't have any custom cards in the allcards.txt file; the extra cards are defined in a separate .txt file and have images contained in a new subdirectory of sets/setimages.

you can do that, but then allcards.txt wouldn't load. so it's either/or if it's a separate file. in order to play your custom cards with Wizards cards, you have to combine them into a big file.

Ah, didn't realise that. It's still perfectly serviceable for drafting a custom set on its own, though, or playing sealed. Or even drafting a block of three custom sets.
