I don't know if you remember, but there was another great website ixmtools.com with a lot of interesting analysis tools, like for example playset costs over time, user card listings with prices when bought and comparison with prices now, so a player would be able to easily find out when cards could be sold for profit... among other tools.

imxtools unfortunately was shutdown and there aren't still any replacements for some of the tools they provided. When you introduced the very practical mass transfer tool you covered one of the things they were popular for.
