tutor.set doesn't get all cards

There's a problem with cards that have different variations, like lands.

For example Plains in M14 have 4 variations, each with a different Artist and Collector's Number.

However, if I `tutor.set 'Magic 2014'`, I get http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=370669 which is not even the first variation.

Unfortunately, due to the way Gatherer works, I doubt that this would be easy to fix.
