Thanks for reply and thank You about the hint with card names ( i did not check that ). I tried to add the cards manually and it worked. There are only ~60 cards with wrong names, so I'm going to add them manually.
As for importing. First, my decks were created. Then I used options from Deck Tools: "Deck Tools -> Add cards to collection -> ( all cards are sellected by default ) -> Add to collection".
Regards
