I was playing Arena, and this interaction didn't make sense to me.
An opponent cast Minimus Containment on my Pacifism to free up their creature. So, it turned into a Treasure token. If I disenchant or remove Minimus Containment from the battlefield, what happens to Pacifism? Do I get to put it on a creature? Arena put it into the graveyard.
While enchanted with Minimus Containment, your Pacifism stops being an Enchantment - Aura. Due to not being an Aura, it can't enchant anything, so it becomes unattached from the original creature.
Then, when Minimus is removed, Pacifism goes back to being an Aura. There's no rule that says a permanent already on the battlefield that becomes an Aura gets attached to a new object, so it stays unattached. And an Aura on the battlefield that's not enchanting something goes to the graveyard.
704.5m. If an Aura is attached to an illegal object or player, or is not attached to an object or player, that Aura is put into its owner's graveyard.
