So, Tosh turned me on to this, and I really like it. Basically what it does is, for the websites specified, it recognizes card names (provided proper spelling) and turns them into link for the card on MagicCards.info. It essentially gives you autocard links in whatever website you want (namely, The Source).

Just follow the instructions on the site, download the GreaseMonkey extension for Firefox (sorry, IE users), then download and install the user script. What you end up getting is this:



Now, that's all well and good, except that the links, IMO, are fucking ugly. So, being the nice person/awesome guy that I am, I dug into the source code and figured out how to modify it so the links look a little prettier:



And, I'm such a nice guy that instead of giving you complicated instructions on how to modify it yourself I just made an alternate file.
Click here for it.

Now, it doesn't have the Source included in the list of sites it automatically works for, but you can add it by going to Tools->GreaseMonkey->Manage User Scripts, then click 'Add'. It will default to "http://www.mtgthesource.com/*" (the * is a wildcard), but it's better to use "http://www.mtgthesource.com/forums/showthread.php?*" so you don't have card links from the main page.

Then, if you ever wonder what a card name is, you can just click, and it will pop up. Pretty nifty, if I do say so myself.
