I deal with Writer's Block by reading something extreme, either a great book or a simply awful book. Great books are inspirational and terrible books are an ego boost.
Television scratches the same creative itch.
I'm a member of a writing group called Clockwork Storybook. Someone, Bill Willingham if I remember correctly, came up with the concept of the IDEA BUCKET. As fast as we empty the bucket by getting the ideas out and onto the page, more come rushing in.
If all of that fails, just get that deck of cards John August created.
