Warp World

Anything that triggers during the resolution of this will wait to be put on the stack until everything is put onto the battlefield and resolution is complete. The player whose turn it is will put all of their triggered abilities on the stack in any order, then each other player in turn order will do the same. (The last ability put on the stack will be the first one that resolves.)

4) Each player puts all artifact, land, and creature cards revealed this way onto the battlefield. All of these cards enter at the same time.

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 who created it.
