Landfall —Whenever a land enters the
battlefield under your control, you may mill
three cards. Add one mana of any color for each
land card milled this way.
{x}{b/g}, {t}: Exile target creature card with mana
value X or less from your graveyard that was put
there this turn. Create a token that's a copy of
that card, except it's a black and green Spirit in
addition to its other colors and types.
