I was looking at Contingency Plan and found the effect surprisingly similar to the keyword Surveil. To compare, first the wording of Contingency Plan and then the wording of the Surveil keyword:
Look at the top five cards of your library. Put any number of them into your graveyard and the rest back on top of your library in any order.
701.41a To "surveil N" means to look at the top N cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.
They quite clearly are the same, so can I assume the card states "Surveil 5" instead? And if so, does it trigger abilities which state "Whenever you surveil ..."?
