Blightning, Killer Groundhog

When Blightning, Killer Groundhog attacks, you
may destroy target creature you control. It can't
be regenerated. You reveal cards from the top of
your library until you reveal a creature card. Put
that card onto the battlefield and shuffle all other
cards revealed this way into your library.
The killer groundhog baffled everyone when it stood
tall and said "Now It's time to be greedy. Time to see if
what comes next is as big as this flavor text", breaking
like this the forth wall.
