Sorcery
Amass
Oozes
X,
where
X
is
the
number
of
creature
types
among
creatures
on
the
battlefield.
Don't
count
changelings.
That
would
be
ridiculous.
(To
amass
Oozes
X,
put
X
+1/+1
counters
on
an
Army
you
control.
It's
also
an
Ooze.
If
you
don't
control
an
Army,
create
a
0/0
black
Ooze
Army
creature
token
first.)
