Ok, so as we all know Big Man is the best character in the game, and for future Splatfests I'll probably be on his team a lot, but rock is just the best option here for two reasons: 1. I have a friend who ALWAYS goes with scissors first, so I can always go with rock to beat him. 2. The color for Team Rock is blue, which happens to be my favorite color. There are 9 (aka 3x3) triangles in the text, can you find them all?
