10/1/2009: Tokens are permanents but not cards. They'll count toward the number of permanents shuffled into your library, so you'll get a card back for each token you owned. But the tokens themselves should be ignored while you're revealing *cards* from your library. In practice, you shouldn't actually shuffle them into your library since they'll cease to exist as soon as
Warp World finishes resolving. Note that a token's owner is the player under whose control it first entered the battlefield; this is a change from previous rules.
