Assemble the Players

You must pay all costs and follow all timing rules for spells cast from the top of your library this way.

You can look at the top card of your library whenever you want (with one restriction; see below), even if you don't have priority. This action doesn't use the stack. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand.

If Assemble the Players leaves the battlefield and returns to the battlefield in the same turn, the casting permission granted by the old one is different than the casting permission granted by the new one. Similarly, if you control multiple Assemble the Players, each one has a different casting permission that may be used once each turn.
