It has to be the guys that complement each other. Three guys who are used to carrying the puck over and over again wouldn't work in the long run, or even short run I don't think.
Here is one, and I wish they had more time to work together, but Lemieux-Sakic-Iginla from the 2004 World Cup would have been nice. Two highly skilled passers who can still shoot through the door of a fridge but have a trigger man on the right side. I think it was one of the games vs. Slovakia where they had one of those rare tic-tac-toe goals that was just epic.
