Expedition Scavenger

Expedition—Whenever Expedition Scavenger
attacks, you may search your library for a land
card, put it into your graveyard, then shuffle. If
you do, create a Scrap token. (It's an artifact with
"{2}, Sacrifice this artifact: Put a +1/+1 counter on
target creature. Activate only as a sorcery.")
The surviving tribes of the Planecleansing depend on
ancient technology and hidden relics to keep their
societies afloat.
