I don't really know how many to aim for, but for me personally, I aim to get as many 1-drops as I can, if the faction has good ones (Spoiled Aristocrat is great, Elf Scout is good, the 1-drop Goblin is good) since there are so few 1-drops and even fewer actually useful 1-drops. Now a lot of the 1-drops are somewhat specific or focused mainly on aggressively strategies (like Lizard Barbarian or Zombie Legionaire). So, I try and aim for 1-drops that are good on turn 1, but also okay later on and I pick them pretty highly, because it feels like I never have enough.
For 2-drops (as in 2 mana, one level), you want at minimum 3 I would say, at least if you're in Elves, since they have Elf Warrior (good!) and the 2/1 Fairy (decent).
I'm no expert on curve though, so take this with a grain of salt.
