The Spirit creature token from Innistrad isn't included in your card database. (http://magiccards.info/extra/token/innistrad/spirit.html)

Hello,

We do not keep track of token cards anymore. There are a couple of really old ones still in there because they were included in Gatherer at some point, but Wizards is not including them anymore. As we get all our data from the official database, from them, we don't by default import these into the database.

It is a possibility that we will get them from magiccards.info at some point, but they're not a priority.
