Murderooze Growth

All your creatures get +2/+2 and trample until
end of turn. For each creature that dies this turn,
you create a 1/1 green Ooze creature token.
At the beginning of the turns end step put
a +1/+1 counter on all creatures you control.
"The Oozes and Slimes flowed and melted into
each other, creating much larger versions of once
harmless creatures. Then they startet to grow and
mutate again, creating even more strange and
terrifying shapes and forms."
