My main source of silver actually comes from attacking low def. players (I know, it's mean). Occasionally you can get 50k from some players but on average I get about 10-15k per attack. Of course, silver aquisition increasing daemons will help you tremendously too.

If you don't want to do that, then storymode+daemon selling is the next best alternative.
