Your objective should depend on the relative skill levels. Compete against equals, teach your inferiors, and learn from your superiors. In a teaching situation, throwing a game isn't helpful. Sharing information—e.g., now I'm going to do such-and-such so I can summon an Air Queen by Turn 20—is likely to help your friends become better players. When they are closer to your skill level, then you can go all out.
