If you delete the game and reinstall all of your cards will be there.

You can transfer the game back to your iPhone by creating a password, but unless you created a password for the device you moved it to (and now intend to move it from - iPad) you won't be able to play the game because it will not let you create a new profile on your iPad. You WILL be able to restore the original game back to the iPad if you created a password for it before you overwrote it.
