Dark Prophet's Mirror

When this artifact enters the battlefield, create a
1/1 Clone creature token with changeling. You
may have that token enter as a copy of another
target creature you control, except it has
changeling, has base power and toughness 1/1,
and is named Clone. Whenever a creature enters
the battlefield, you may have the Clone become a
copy of that creature, except it has changeling,
has base power and toughness 1/1, and is named
Clone. --- Disturb {3}{b}{b}
