The Advanced Tactics are starting to go up. Since I've written them, the information is certainly a little dated, but it'll give you a good idea of things that are/have been possible in GC, and you can use these ideas as starting points for potential new tactics. The ideas presented there in should work on some level at the very least. More Advanced Tactics will follow as I isolate specific tactics. Certain users may start to contribute their own tactics at some point.
