You can also grab the Shiva card from Zone on the Timber Owls hideout train. Actually, it's preferable you get it from him then because the next chance you'll get won't be until he's on the White SeeD ship, which plays with Centra rules (Random is bad apples).



edit: No wait, that's wrong. Just looked it up to make sure. Turns out you have to grab the 'Girl Next Door' magazine from the Timber magaziney/newspaper place and give it to Zone. I think you'll have a chance to do that as he gives you the tickets to the train to Galbadia when he's dressed as an old man.
