Friend to Nature - If this card is in your opening
hand, you may reveal it. If you do, exile it and
create an Emblem with "If you revealed a
companion this game, you may pay {0} to add that
card to your hand. Activate only as a
sorcery."
{2}{t}: Search your library for a creature with Companion. Put that card into your hand then shuffle.
