L'thl the Avoiding

If L'thl would leave the battlefield, you may pay {g} and sacrifice a land instead. If you do,
L'thl gains shroud and unblockable until end
of turn. (Destroy, exile, and -*/-*effects end, remove
any -1/-1 counters, return to hand or put to library
effects don't happen, and damage resets.)
Whenever L'thl deals combat damage to a player,
search your library for a basic land card, reveal
it, put it into your hand, then shuffle.
"You don't see me."
