For what it's worth, I have related projects on Github (although they haven't been updated in a while):

https://github.com/zephyrfalcon/magicripper2 (to scrape cards from Gatherer)

https://github.com/zephyrfalcon/magicquery (to query the card database)

I also made a set of files (not on Github (yet)) that indicate a card's keywords and other properties (e.g. flying, protection, split card, etc etc). I found it very hard (read: ~impossible) to extract this kind of info reliably from the card text.
