OK. So to clarify.
When the 2 mana is paid and the matrix of energy is established by your opponent, you pay the 5 reveal cost and reveal reverse magic and gain control of the face down enchantment, you can then look at it and decide if you want to pay the reveal cost and activate it right then and there, or just choose a new target and place it face down on it to reveal when you are ready.
Am I understanding this correctly?
