So i was toying with filters and suddenly Banish filters dont show any cards even with no filters just Any and Banish but if i check at general i can freely see Banish cards this effects all my decks

Works fine for me. Please provide a screenshot of your deck filters configuration.

that's indeed strange. My search works fine but I managed to reproduce your same results typing two space characters in the search field, but I don't think this is the problem.

Make sure the name filter contains no characters. As Fithz Hood pointed out, if you put two empty spaces into the card name filter you will get empty result set.

There are no letters spaces . / [ ] or w.e its absolutely blank

I know what the problem is:

there are no banish support cards :)

but i havent set ANY filter?

Lol, so true, I wonder how I'didn't see it.
If you are looking for a keyword you need to use the second filter. The fifth one you have used is the "support" filter: it returns any card that has the searched keyword written in its text.

Maybe a message could be added to results if no cards were found, like "No cards matching this criteria".

Oh ok then my bad....again

Actually there is a way - if you look at the 'hide card pool' button. If it's green there are some cards in result set, if it's not (has standard layout) there are no cards in result set.

I had the same problem with the only keyword I've searched for since returning to the site; alliance. Selecting it and applying filters results in no pool of cards.
It could easily be a general thing about how keywords are searched for.
Also, could it have anything to do with that option the decides whether keywords display as icons or words?

The display option for keyword insignia does not effect card search, it's only a display feature.
