Dread Summons

Sorcery

Each player mills X cards. For each creature card put into a graveyard this way, you create a tapped 2/2 black Zombie creature token.

2015-11-04:
If a creature card has an ability that replaces going to the graveyard with moving somewhere else “instead,” that card won't count toward the number of Zombies you get. Conversely, creature cards with a triggered ability that removes them from the graveyard when they're put there from anywhere (or your library) will count toward that number.
