Edit: now that I think about it, yeah, they still do, but only for standalone expansions, I believe.
Anyway, as I remember tourney packs have 60 cards....I believe 3 random rares, I think it's 12 random uncommons (something like that) , five basic lands of each type from the latest standalone expansion and then the rest are random common cards.
Don't quote me, since the last Tourney pack I bought was from Urza's Legacy.
Tourney packs are good to get when you need basic land. Generally I would just get a tourney pack to start, and they even substitute as deck holders.
Oh, I also remember back when the base set tourney packs used to come with mini-rule books (By the way there is a magic rule that states "Ignore this rule" :laugh

and select expansion ones came with storybooks. Good times.
