You can only equip this card to a monster on your side of the field. Decrease the ATK and DEF of a monster equipped with this card by 500 points. In addition, all the monsters on your opponent's side of the field can only attack the monster equipped with this card, if they attack.
does it stack with, say, Freya, Spirit of Victory? For instance, if I equip it to Freya while another fairy is on the field, does Freya's effect make it so the opponent cannot attack it while at the same time the RoM makes it so the opp can ONLY attack it, pretty much making her invincible as long as there's another fairy on the field?
