You can clone Pokemon without an AR by going to battle tower, depositing the Pokemon to be cloned in an empty PC box, exiting and saving, then taking Pokemon out and taking battle tower challange. While the game is saving after talking to the receptionist, turn off the game. When you turn it back on, check you PC box. The Pokemon you deposited will be in the box and in your party.
Turning off your game while still saving can cause data loss and permanent damage to your game so I don't suggest you use this method unless you're desperate or using an emulator.
