When an opponent targets my Jae Medarda with a spell, do I draw a card?

Ruling: No. In Riftbound, "you" in card text refers to the controller of the card. Jae Medarda's ability "When you choose me with a spell, draw 1" only triggers when you (the controller of Jae Medarda) target her with a spell you control. When an opponent targets Jae Medarda, the ability does not trigger because the opponent is not "you" (the controller).

Nuances:

• The "you" in the trigger condition refers to Jae Medarda's controller, not just any player.
• If you do trigger the ability by targeting your own Jae Medarda, you draw the card as the controller of the permanent.
