Plane — Ravnica
Whenever
a
creature
dies,
its
controller
distributes
a
number
of
+1/+1
counters
equal
to
its
power
among
any
number
of
target
creatures
they
control.
Whenever
chaos
ensues,
each
player
exiles
all
creatures
they
control
and
creates
X
1/1
green
Saproling
creature
tokens,
where
X
is
the
total
power
of
the
creatures
they
exiled
this
way.
Then
planeswalk.
