Nonne, Scale Crown

When Nonne, Scale Crown enters the battlefield,
create four 1/1 green Lizard creature tokens.
Whenever a Lizard creature dies, target creature
gets a -1/-1 token.
When a creature with a -1/-1 counter(s) dies, put
those counters on another target. If no targets are
available, target player takes damage equal to the
number of -1/-1 counter(s).
