This won't be one card, it's a mechanic. I'm trying to see how to break the white return cards from opp gy to hand which shows up on several white Judgement cards. One lets you return a creature from your own gy to play, another prevents damage, etc. This seems breakable. With Blue you could use Traumatize to get cards there, and return lands to their hand. Maybe black/white discard? The problem with discard is they run out of stuff to force to discard, this way they'll have it again. I'm curious to hear your ideas.
