I'm new to using this site and absolutely love it.
Maybe this is already featured somewhere and I just couldn't find it.
It would be nice to set some inventory filters - maybe a set of check boxes that started ruling out cards based on rules. Something like this:
_ Standard
_ Modern
_ Legacy
_ Vintage
_ Block ---- drop down with block
_ Pauper
_ Peasent
_ Noble
Selecting each one would cause non-legal cards to be filtered out showing what you can build for that deck format.
great site
