Fresh Meat puts a 3/3 Beast token into play for each creature that has gone to your graveyard prior to when Fresh Meat resolves. This ability will count token creatures that you own and control, as token creatures that are destroyed do go to the graveyard. However, it will not count any creatures that you have ‘stolen’ that die this turn. This is because when a creature goes to a graveyard, it goes to the graveyard of its owner. Fresh Meat will not ‘see’ these creatures and not count them.
