A ninja waits until the time is right. When the enemy sleeps and drops his guard. When his weapons lie forgotten in the stillness of the night...
A trade war is when one person (usually entitles trade "trade war" ) puts out an item originally with any value: it can be high or low. The next person has to try and top it with either gold or another item. You each try to top each other until one can't or gives up.If you accept the trade, that's basically a white flag of surrender. Winner gets bragging rights and you both go off to bask in your new items. :3
...That is the moment for a ninja to strike.
