Animate Graveyard

If there's a creature card in your graveyard with an ability that defines its power and toughness, such as Tarmogoyf (Maro: He means Maro), the ability of Animate Graveyard will apply after that ability. The base power and toughness of your graveyard-creature will still be equal to the number of cards in your graveyard.

While you'll use the cards in your graveyard to determine the stats and abilities of your graveyard-that's-a-creature, those cards aren't themselves on the battlefield. For example, if you mill a card while your graveyard is animated, the milled card doesn't enter the battlefield. This isn't quite as wild as Yet Another Aether Vortex.

Once enchanted, your graveyard behaves like any other creature. It can attack or block. You can enchant it with other Auras, equip it, use it to crew Vehicles, and so on. It won't naturally have any creature types—the text box doesn't include the type line.

Similarly, if Animate Graveyard leaves the battlefield or becomes unattached from your graveyard, the animated graveyard will return to being just your graveyard.

If the enchanted graveyard would leave the battlefield for any reason, instead Animate Graveyard is exiled. This will cause the graveyard to give up its dreams of being a creature and return to being only a graveyard. The graveyard doesn't die. It just goes back to being a graveyard. No abilities that trigger whenever a creature dies will trigger.

Your graveyard-creature will have all the text boxes of all creature cards in it. This means it will have all rules text, flavor text, and watermarks of those creature cards. If a creature card is put into your graveyard, the graveyard-creature will gain its text box. If a creature card leaves your graveyard, that text box will be lost. Phoebe can steal any of these text boxes, but she must do so one at a time.
