While I was searching for cards to go into a new deck I had the idea, that it could be greatly enhanced by tags for the cards.
To illustrate, some examples of what I am thinking of:
1) To find card drawing spells, you can filter for the rules text "draw". This will, however, also show all cantrips, all cards with cycling, etc . With card tags you could simply filter for the tag "card_draw" (or sth similar) and find your results.
2) Similarly, you could find cards, that use counters, for your Doubling Season deck without finding most counterspells or if you were to seek for counterspells you would also find Mindbreak Trap and the like.
3) If you want hosers for a suspend-deck, you search for the appropriate tag (e.g. suspend_hoser) and find Riftsweeper.
It would obviously take a lot of community effort to tag all cards, but the result would be the best search engine for cards I have seen so far. What are your thoughts on this?
