Ojutai's Command

If a Command is copied, the effect that creates the copy will usually allow you to choose new targets for the copy, but you can’t choose new modes.

As the spell resolves, follow the instructions of the modes you chose in the order they are printed on the card. For example, if you chose the second and fourth modes of Ojutai’s Command, you would gain 4 life and then draw a card. (The order won’t matter in most cases.)

You choose the two modes as you cast the spell. You must choose two different modes. Once modes are chosen, they can’t be changed.
