Scrapyard Purveyor

Whenever Scrapyard Purveyor enters or
attacks, create a Junk token. (It’s an artifact
with "{t}, Sacrifice this artifact: Exile the top
card of your library. You may play that card
this turn. Activate only as a sorcery.”)

Whenever an artifact you control leaves the
battlefield, put a +1/+1 counter on target orc
or goblin creature.
