The Audacious

When The Audacious enters the battlefield put a
+1/+1 counter on each other creature you
control.
At the beginning of your upkeep put a
+1/+1 on target creature you control and each
other creature you control gains trample or reach
until your next upkeep.
When The Audacious dies or is put into exile
from the battlefield, you may put it into its
owner's library third from the top.
