Discarding Your Own Cards

I was surprised to see no cards that had to do ultimately with discarding your own cards. Sloppy research is exactly the same card, but you have to discard a card too. It's even called sloppy. But of course, it's an advantage because it allows you to do this sort of card cycling. There is not anything that I can think of where you discard cards from the same house as a cost to them. That could definitely be used.
