Griffin Hatchlings

If Griffin Hatchlings are dealt damage by a
source an opponent controls you may search
your library for a griffin creature and reveal it. If
that creature's converted mana cost is less than
the amount of damage done to Griffin Hatchlings
you may put that card onto the battlefield under
your control, otherwise put that card into your
hand.

Chirp-chirp, cheep-cheep-SCREECH!
