Gitalon, Beast of the Depths

When a beast creature enters the battlefield
target creature gets +2/+2 until end of turn. You
may also look at the top 10 cards of your library,
if you do, choose one —
• Put all the creature cards you find there into
your hand. You have no maximum hand size.
• This ability acts as if you were scrying 10.
• Exile all the cards. If you do, target creature
gets +6/+6 and gains vigilance and deathtouch
until end of turn.
