Ominous Harvest

Gravestorm counts all permanents put into graveyards from the battlefield this turn. It doesn't matter who controlled those permanents, who owns them, or whether or not they were tokens.

You may choose new targets for any of the copies. You can make different choices for each copy.

The copies of Ominous Harvest created by its gravestorm ability are created on the stack, so they're not cast and won't cause abilities that trigger when a player casts a spell to trigger.
