Miro, the grove guardian

When Miro, The grove guardian enters the
battlefield, you may search your library for forest
cards equal to the amount of forests you control
and put them into play tapped.
Creatures you control gain hexproof.
When Miko, The grove guardian dies, reveal
cards from the top of your library until you find
a nonland card. Put all cards revealed this way on
the bottom of your library and draw cards equal
to the mana value of the nonland card.
