Obsidian Adjudicator

Indestructible, protection from instants and
from sorceries
Whenever Obsidian Adjudicator enters the battlefield or attacks, reveal the top five cards of
your library. An opponent separates those cards
into two piles. Put one pile into your hand and
the other into your graveyard. Then, if three or
more artifacts are revealed this way, you may
return target artifact from your graveyard to the battlefield.
