Reliquary Fiend

Relicbind {1}{r} ({1}{r}, Exile this card from your hand: When target noncreature artifact is put into a graveyard from the battlefield, put this card from exile onto the battlefield under that artifact's controller's control.)
When Reliquary Fiend enters the battlefield, sacrifice all artifacts you control.
Freed, it lashed out at the other relics, lost, bewildered in a house of peace.
