Shikamaru, Lazy Genius

While Shikamaru is in play, you may look at the
top card of your library at any time.
Whenever Shikamaru attacks, you may draw a
card or put it on the bottom of your library. If
you choose to put the card on the bottom of
your library, tap a creature an opponent controls
with power equal to or less than the converted
mana cost of the card placed there.
"What a drag..."
