"A single grain of sand is insignificant, but a sandstorm can reduce pyramids to dust. Stand with your crop. Become the storm."
—Oketra, god of solidarity

Amonkhet

The set of creatures affected by In Oketra’s Name and how those creatures are affected is locked in as In Oketra’s Name resolves. Creatures you begin to control later in the turn won’t get any bonus, and creatures that start or stop being Zombies later in the turn won’t have their bonus changed.
