I loved this one, even though it didn't focus on the three main ladies. Riddler is my favorite villain so an issue all about him is always great in my opinion 😉 and the new Riddler-Replacement, Conundrum was a good idea because:
1] It gave us a girl villain, so it's still loyal to the book 😉
2] She matched wits with Riddler, which is certainly interesting
Hope we see more of her down the road
