Karina and Death Marshal combo question

[Hawkman67609er]

What happens when Karina uses faces of the oblivion to summon a model and a death marshal pine boxes it but the ability that summoned the model says at the end of turn the model takes damage, gains slow, and is buried. Does it still take damage, gain slow, and rebury itself if it's already buried?

From page 47: "Buried models still process Conditions and other effects that happen at the end of the Turn...", the damage and slow from Faces are examples of "other effects" so they happen. "Rebury" is not a thing though as you can't be doubly buried or something like that, you are either buried or not.
