Great Post!!!

I was discussing this with @rentmoney and @aussieninja only yesterday evening.

Packs are awesome if you like to play the lotto, and I think we all do from time to time, but if you want to build a seriously competitive deck I think it's best to buy cards individually and save the packs for another time or use.

Like you also mentioned, buying in bulk during pre-sales, and selling for a small profit to buy the individual cards you need seems like a pretty solid tactic I imagine most of the players with the most impressive collections share.
