Slithering Hydra

Slithering Hydra enters the battlefield with X
+1/+1 counters on it.
Haste, deathtouch
When Slithering Hydra attacks, you may look at
the top X cards of your library, where X is Slithering Hydra's power. If you do, you may
put up to one Forest card from among them into
your hand. Put the rest of them on the bottom of
your library in a random order.
