As some of us have said before, it would be much better to fix the current bugs before starting to implement new cards. I'm not necessarily talking about all bugs; there are probably some that are very rare and difficult to pin down. But the vast majority of the bugs should be fixed. Many of them have been present since launch, and adding new cards first that will inevitably introduce new bugs doesn't seem like a good idea. There's also missing functionality that should be implemented first, like being able to view full logs of past games, deck contents at end of game, and missing info in the running game log. There are also several problematic interface issues (that you could count as bugs).
