T'Ylera, Cavern Queen

For each spore counter on them, Fungus and Saproling creatures you control gain +1/+1 and other creatures gain -1/-1.
At the beginning of your end step, put two 1/1 green Saproling creature tokens into play.
Whenever a Fungus or Saproling creature enters the battlefield under your control, put a spore counter on target creature.
