Oso, Ever Loyal

When Oso enters, 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 "Tap, Sacrifice this artifact: Exile the top card of your library. You may play that card this turn. Activate only as a sorcery.")

"Oso, do you want some chocolate?"
