Catalogue 3 (As this enters the library zone, put the
top three cards of a library you own face up on top of
this card as a new library. As this becomes empty, put
it into its owner's graveyard.)
Whenever you draw a card from this library, you
may look at the top three cards of target player's library. If you do, put up to one of them on the
bottom of that library, and the rest on top in any
order.
