Olav's Meandering

Whenever three or more land cards are put
into your graveyard from anywhere in a
single turn, you may return a land card from
your graveyard to the battlefield tapped.
"Olav has no care for the weariness and sorrows
of the world. He revels in the present moment,
the cyclical song of nature, and his purpose is to
be with it, to partake in it's fleeting joys."
