@JonTheMon I don't agree with the random discard remedy. Per the IPG, "Remembering one’s trigger is always the responsibility of the player who controls the ability." Taking away a player's ability to choose punishes that player, and rewards the opponent whose responsibility it was to remember the trigger in the first place.

So, based on your response, the player who would have been Expert'd gets to decide if the trigger goes on the stack or not at that point? So instead of "closest to ideal" it's "punish the one who missed the trigger"?
