Xylina, Wandering Summoner

Secretive -- When Xylina, Wandering Summoner
enters the battlefield, search your library for up
to three creature cards, exile them face down,
then shuffle your library (You may look at those
cards any time.)
{x}, {t}: Reveal a card exiled with Xylina and put
it into your hand. If that card is a creature card
with converted mana cost X, create a token that's
a copy of it except it has haste.
