Small but effective Research

Choose creature or non-creature.
Then look at the top four cards of your library.
You may reveal a card of the chosen type and put
it into your hand. Put the rest onto the bottom
of your library in any order.
If you copied a spell this turn, you may reveal
both a non-creature and a creature card und put
both into your hand. Put the rest onto the
bottom of your library in any order.
