March, the Mad Hare

Menace
{t}{x}: Lose X life. X target creatures lose all
creature types, then you may assign each of
these creatures a type, but only a type lost this
way. Illusions targeted by this ability are not
sacrificed in response, and creatures that gain
the Illusion type must be sacrificed at the start
of the next end step. * then becomes equal to
the number of creatures sacrificed this way.
