You can now build your own decks under “Decks > New deck” 
Right now, it is not saved in our database, but you can bookmark it in your browser to save it. You can also copy the link and send it to someone to share your deck with others.
My general ideas for the future:
- Save the deck in your account
- Add an ability to share the deck publicly on the site
- Save/Vote on/Like public decks and have a ranking of most popular ones
