How can I find all cards?

Hello, I play TCG live, and it's a lot of fun. Now I want to build a new deck, but I noticed that I can't select all the cards. For example, I can't find OBF 223. I've also noticed that many of my opponents have some gold cards (energy or Gold Mew) in their decks, but I can't see these cards to add them to my deck, even though I've chosen the 'all cards' option. What do I need to do to see and select all cards?
