Niten, Ghrattan Explorer

When Niten deals combat damage to an
opponent if he wasn't blocked search
your library for a basic forest and put it
onto the battlefield tapped, then exile Niten
and choose target non-basic land, the next
time that land would tap for mana you may
use that mana to cast Niten, If you do not
control a non-basic land card exile Niten.
I don't do it for fame or adoration, I do it
for Ghratta Grove, I do it for humanity.
