Primal Revelation

Whenever a nontoken creature you control with
3 power or less is destroyed, you may pay {g}. If you do, put it on top of its owner's library.
Whenever one or more +1/+1 counters are put
on a creature you control, draw a card.
All life is equal in their struggle to survive; nature ensures the meek are plentiful and the hunters few, so that each have their opportunity to live.
