MtG Inventory and Deck Builder application
What initially started out as a fun little research project has bloomed into a delightful little Grails program no thanks to the impeccable data provided by mtgjson.com and mtgimage.com
I currently have no intent to serve this on a website somewhere unless enough interest is found.
Otherwise, it's pretty dead-simple to start a Grails app. grails-run and you're good.
