Some find their own minigame in this. One good friend of mine is apparently in it to produce the most powerful deck at the lowest cost - usually via second-hand purchases. Others just fish for foil cards, which apparently are measurably heavier than normal ones and with a precision scale it's possible to tell whether a booster has one. I'm not a collector, so I stopped buying them when power creep rendered a second deck of mine useless already.
