Here's the card and skill game data in JSON format, I'm not sure if they belong on the wiki so I uploaded them to Gist. Feel free to copy them to the wiki but they're a bit long.
Card data: https://gist.github.com/anonymous/5eb5168fd13a4ffd6939
Skill data: https://gist.github.com/anonymous/0aeb9d7cb82393430d00
HD card images: http://valkyriecrusade.wikia.com/wiki/List_of_high_quality_card_files
"card_no" will match the image card number.
"skill_id_1" and "skill_id_2" will be linked to "_id" in the skill data file.
I updated the stats for a few cards that you can use as an example on how to use the data.
Edit: I just noticed that the max stats for the evolved cards only show the stat without the 30% bonus. So you'll need to add 30% of the original max value to the evolved cards's max value. Thanks to Gorou for correcting the stats.
