Legendary Creature — Dog

When Dogmeat enters the battlefield, mill five cards, then return an Aura or Equipment card from your graveyard to your hand.

Whenever a creature you control that's enchanted or equipped 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.")
