Did search for this one but didn't see anything obvious.

When deckbuilding, it would be helpful to click on a card and have a heading called "Similar To:", where based on the rules text it could suggest cards that are similar in purpose. Doesn't have to be exact but having this feature on the card screen without having to search by the rules text would speed things up.

Excellent site I really love all you've done here, thanks!

I've considered requesting a couple variants of this put it would require, for starters, a complete overhaul of the current rules text for all cards and/or someone who's job was to match cards (or at least, to moderate the matching)
