As an aside, Falkenrath Aristocrat still sees a lot of play in the European Highlander format in a deck known commonly as 4-Color Blood. It's a 100-card singleton format like Commander, except without a Commander. It's a cool format, actually, so she'll still being seeing play there.
While she wasn't an expensive card as of her reprint, around $3, she'll now be extremely cheap. She doesn't really see any play at all in Modern, but she's still a decent card to have at rare. But without a huge amount of competitive demand (outside of European Highlander), she'll be a very cheap card before long.
