Quick Thinking—You may pay {4}{u}{g}, and cast
this spell as though it had flash.
Search your library for a creature card, reveal it,
and put it into your hand, shuffle, then reveal
the top 3 cards of your library and put all
creature cards revealed this way into your hand.
If this spell was cast on another player's turn,
counter target spell with converted mana cost
equal or less to that of a card you revealed this
turn.
