Replace a random card in game (both hands) with self


If I understand the last line correctly, I'd word it this way:

Replace a random card in game (either player) with self

...so it doesn't sound like BOTH players will receive one.

True. That was my intent. I think that just using "in game" should be sufficient, I just wanted to make it more clear. I don't think we currently have such a card in game. A persistent card that can randomly move to either player's hand. That is the main concept. Maybe the effect is too powerful or too weak.
