Ozeir, Forsaken Archdruid

At the begining of your upkeep, you may
sacrifice a nontoken creature. If you do, exile it,
and you may search your library for two forests
and put them into play.
{b}{b}{r}{r}, Sacrifice 2 or more untapped forests:
Green creatures you control gain haste, menace,
and +1/+1 for each forest you sacrificed this way.
