Theres a couple of superstitious things that I like to do before each game.
I usually sweet talk the marshall who's reffing my zone
I like to put swollen paintballs in the other team's loaders
When the other teams left their guns on the table in the crony station, I find it helps to go around and turn the air off on their guns
Its just little things like that really that help to get me in the zone for the match ahead.
