Fae of Conception

When Fae of Conception enters the battlefield, chose an opponent. If that opponent attacks you or targets a permanent you control, flip Fae of Conception.
At the beginning of your upkeep, roll a six-sided dice and activate the effect based on the result:
1: You and chosen opponent draw a card.
2: You and chosen opponent both give a target creature they control regenerate {p/r}{p/r}.
3: Creatures can't attack you or the chosen opponent
