Norin the Cursed

When Norin the Cursed enters play, search your library for a card, put it into your hand, then
shuffle your library.
If a creature goes to your graveyard from play
while Norin the Cursed is in it, return him to
play under your control. If he would enter play
any other way, return him to your hand instead.
If he is in play and a spell is cast or creature
attacks, shuffle him into your library.
