See Arrows for my system of Arrows. (You only need to read the first few sentences to get the idea.)
The point of this particular deck is to react violently whenever someone hurts my board state. So if you have the current "Arrow", you will pay dearly for your crimes against me. If no one has an Arrow, I usually just attack the person with the highest life or the best board state.
