EDIT: Your report page is bugged and doesn't give me the option to pick the category game play report bug. See Screenshot.

I also wanted to report on the card. Offspring's revenge on a possible bug.

Opponent has offspring's Revenge with a lot of creatures in their graveyard.

Like a drakuseth dragon. I used a Elspeth nightmare to eventually empty their graveyard. The opponent is still able to access their grave yard exile to use their offspring's Revenge. Is this bugged? They didn't target any card from their graveyard. There's nothing there.
