Conspiracy is awesome. What I consistently do is draft like three conspiracies that have me name a card to benefit, and then draft a bunch of an underpowered card that no-one else wants. When I did it two weeks ago I drafted five copies of Syphon Soul and the conspiracies so that it cost 1 less, was doubled, and drew me a card. Suddenly five copies of a 1B spell that does 4 damage to everyone, gains me that much life, and draws me a card is really good.
That's pretty fun. I never really drafted the conspiracies themselves, other than one that made my wolves able to tap for mana. Wish I could draft conspiracy more -- nobody around here wants to play it, it seems.
