Clarification on Millennium Rod - Scepter of Supremacy

New to playing and enjoying it so far!
Question(s) about Millennium Rod - Scepter of Supremacy.
1) If I have Millennium Rod - Scepter of Supremacy fielded, and my wife during her attack phase chooses to attack with Cyclops - If Looks Could Kill, can I then us the ability of the Millennium Rod? Or in order to have used it's control power, would I have had to choose to take control of her Cyclops before she chose to attack with it?
2) Does the Millennium Rod allow me to use the characters abilities, or just the die itself for attacking/ blocking? E.g. My wife has fielded, Red Dragon - Epic Dragon. On my attack phase, I play the Millennium Rod to take control of her Dragon. Can I then, 1) Attack with the die, 2) Attack AND use the Breath Weapon 3 ability?
Thanks so much in advance!
