Witch of the Black Forest

Morph {p/b} or {p/g}(You may cast this face down
as a 0/2 creature for {1}. Turn it face up any time
for its morph cost.)
When this is turned face-up, target creature
must attack this turn.
When this enters your graveyard, reveal a
creature with 3 or less power from your library,
and add it to your hand then shuffle.
