Shady tactics

[bleach168]

Can you guys list the possible tactics that violate a NAP but are shady enough that you can probably get away with them?

For example, you can cast hurricane on your opponent and he will probably think it was a naturally unlucky event.

Also, you can have stealth preachers in enemy territory and as long as they don't get caught, you can do some dominion damage.

Also, does Fires from Afar tell you where the attacks originiated? When I get hit by them, I don't remember it saying where it came from. That could be a nice dirty tactic to use on someone, especially if you're not a fire nation. They would never suspect you.

I'm sure there are more dirty tricks and I'm eager to learn them! (No, not because I'm a dirty player, I just want to know how to spot them so I can defend myself. Honest!!!)
