Natural Competition

Creatures you control gain Evolve. Whenever a creature enters the battlefield under your control,
if that creature has greater power or toughness than
this creature, put a +1/+1 counter on this creature.
During your upkeep, you draw a card. If
it is a creature card, search your library for a basic
land card and put it into play. (This can only
happen once per turn.)
Grow. Expand. Adapt.
