Jia, the Technician

When Jia, the Technician enters play, you may
discard a card. If you do, reveal the top five cards
of your library. Put all instant and artifact cards
revealed into your hand, and the rest on the
bottom of your library in random order.

At the beginning of your end step, if Jia is in your
graveyard and you copied an instant spell this turn,
you may put Jia on top of your library.
