After the tournament, go to see a movie or ballgame together. Modesty and good sportsmanship are necessary of all players, but somehow you MUST crave the feeling of victory. The first rule of being a true sleeper agent is to never give advice to anyone. Some cards are so popular that every person has them in most of their decks. Your time is better spent constructing decks to defeat everyone that sits down to face you.
Good players study the changes and adapt their methods to stay competitive.
