Ashen Ghoul — ruling 1

A card is "above" another card in your graveyard if it was put into that graveyard later.

Ashen Ghoul — ruling 2

Players may not rearrange the cards in their graveyards.

Ashen Ghoul — ruling 3

If an effect or rule puts two or more cards into the same graveyard at the same time, the owner of those cards may arrange them in any order.

Ashen Ghoul — ruling 4

The last thing that happens to a resolving instant or sorcery spell is that it's put into its owner's graveyard. Example: You cast Wrath of God. All creatures on the battlefield are destroyed. You arrange all the cards put into your graveyard this way in any order you want. The other players in the game do the same to the cards that are put into their graveyards. Then you put Wrath of God into your graveyard, on top of the other cards.

Ashen Ghoul — ruling 5

Say you're the owner of both a permanent and an Aura that's attached to it. If both the permanent and the Aura are destroyed at the same time (by Akroma's Vengeance, for example), you decide the order they're put into your graveyard. If just the enchanted permanent is destroyed, it's put into your graveyard first. Then, after state-based actions are checked, the Aura (which is no longer attached to anything) is put into your graveyard on top of it.
