Ritual Gatherer

If this creature kills a creature, search your library
for ether a Forest or Swamp Basic Land and put it
into your hand. Then Shuffle your library, if you
own more then 4 lands, search for any card instead.

"The crazed cultists of that serve the Freylyna and
the Sisters wonder here, make sure they do not gather
in the forests as it they know these lands better then
we ever could."
- Sir Rynfrey, Leading a Assault on Totemwood.
