Arugoni, Dragon Soulsayer

Double strike
{4}{r}{r}, {t}: Look at the top ten cards of your
library, you may reveal a dragon creature card
from among them and manifest it, it gains flying
and haste. Shuffle the rest of the cards into your
library. (To manifest a card, put it onto the
battlefield face down as a 2/2 creature. Turn it face
up any time for its mana cost if it's a creature card.)
