Kind of an extension on Tags for easily searching themes

If you click the cardlist link, you can then Ctrl+F (or equivalent) to find whatever you want. There's no built-in way, however.

Yeah, I'd generally do this via the cardlist. The visual spoiler will also work as long as the cardset isn't so big that the VS gets split across multiple pages.

But yeah, "cardset" is a reasonable extra field to add to the search page, which is pretty basic at the moment.

Of course I can think of the ctr+f thing, but it's at beast a crappy substitute for a straightforward method of listing cards with certain effect.
