Presence of Greatness

At the beginning of your upkeep, look at the top
three cards of your library. You may reveal a
creature card with converted mana cost 4 or
greater from among them. If you do, put it into
your hand and put the rest on the bottom of
your library in any order. If you control a
creature with converted mana cost 4 or greater,
look at the top 4 cards instead.
