Orpheus, the Lovely Chord

When Orpheus, the Lovely Chord enters the battlefield, search your library for a land card or
a creature card with converted mana cost 3 or less
and add it to your hand.
When you have ten or more poison counters,
instead of losing the game, sacrifice a permanent
and remove all -1/-1 counters and poison counters
from you and creatures you control.
