I've been thinking recently about doing the following inventory check on my collection with a simple checklist question: "Do I need this?" If the answer is not an absolute "Hell Yeah I need this!" than the possibility of parting with them is tempting---and those funds could be ploughed into "keeper" cards.

What is your opinion? Should you always be buying cards with the intention that they are in the "keeper" category? Or is it healthy to dabble back and forth and pick up cards that you like at the time but realize could be disposable/substituted for other classic cards down the road?
