Kreature

When Kreature enters the battlefield, you may
search your library for an artifact card with
mana value 1 or less, reveal that card, put it into
your hand, then shuffle.
The house-elves of Hogwarts swarmed into the
entrance hall, screaming and waving carving knives
and cleavers, and at their head, the locket of Regulus
Black bouncing on his chest, was Kreacher: "Fight
for my Master, defender of house-elves! Fight the
Dark Lord, in the name of brave Regulus!"
