Terexos, protector of life

Flying, Trample, protection from black.
If damage dealt to any nonzombie creature
would be enough to destroy it, that damage is
dealt to Terexos, protector of life instead. Put a
land from your hand onto the battlefield tapped.
Whenever a land enters the battlefield under
your control, you may put a +1/+1 counter on
each elemental you control and each dragon
you control.
