I will agree with some of that. Me and my friends didn't get started by buying premade decks, we got started by sifting through our old cards and buying any packs that seemed cool. Before we started playing with the format, packs were packs, and cards were cards. If they seemed usable, we'd try to find a way to use them, and with such a limited collection on us, I think it helped with teaching us how to make interesting decks.
