Buried Alive does not allow you to selet the graveyard order
When Buried Alive is resolved, it does not allow you to select the order of cards placed in your graveyard. As the card does not specify this one way or the other, according to:
404.3. 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.
This affects the interaction of Buried Alive and Corpse Dance in Vintage Cube.
in addition to vintage cube this is a potential issue in player made format some play on MTGO - Premodern as people may use buried alive to get death sparks or to get up corpse dance
Happened to me today. Same thing happens when discarding multiple cards for Collective Brutality.
