I just picked up the King in Yellow xpac and was curious which AO would pair with the Herald to make a more challenging game? My wife & I are experienced players, so learning curve isn't an issue.
Thanks in advance.
Edit: I forgot to mention that we own all available xpacs except for Innsmouth and Black Goat.
