I like the concept, but you really need a "Try it First" option that lives outside the paywall. I am very hesitant to type in my credit card before I have any idea if the service works how I expect. 2 cents.
This is very nicely done. Wish this was available when I was developing CardSplice as it would have saved me some time.
Shameless plug for CardSplice[1] since hacker news is talking about MTG. I had a ton of fun developing this awesome app that lets you quickly feed Magic Cards behind your mobile and uses some advanced image processing and OCR to detect the cards and upload the list into the cloud. Amazing for draft deck building and organizing.
