The problem with defining this format by what is "fun" is that everyone seems to define fun as what they don't lose to. If you keep losing to easily answered cards, that means you should improve your deck. If you don't want to improve your deck, then you should come to peace with the idea that you are going to lose because you chose to not interact with better strategies.
I wish one day they will complete the cycle and make to all the members of the Obzedat their own individual card.
I hope so as well; and I'm STILL mad that Kaya came in and just killed them all off. Hopefully we can get cards of them from a historical retrospective standpoint, because they won't be returning in a standard Ravnica set anytime soon.
As someone who read the first Ravnica block's novels, I'm kinda upset by the notion of Augustin IV being associated with the term "great leader".
Although, the quote is most likely his own, so it's definitely in-character.
I'm mainly just posting this because, while Karlov's card on its own makes it clear he's a bad guy, people who know nothing about Augustin IV might think he was a good guy just going by the card.
