The Sorting Hat

Sorting Ceremony: {3},{t}: Look at the top four
cards of your library. You may reveal a
creature card from among them and put it into
your hand. Put the rest on the bottom of your library in any order. If you reveal a Wizard creature card this way, you may put it onto the battlefield instead.

House Selection: {1},{t}: Choose a color.
Creatures you control gain protection from the chosen color until end of turn.
