Be Fruitful And Multiply

Whenever a creature you control dies, create a
1/1 green Saproling creature token.
Whenever you cast a creature spell, you may pay {g}. If you do, put a +1/+1 counter on each
creature you control.
And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and
subdue it: and have dominion over the fish of the sea,
and over the fowl of the air, and over every living
thing that moveth upon the earth. - Gen 1:28
