Manfred is okay in my book. Since Sasha, Falkenstein, etc. are hard to justify pilling against, his confidence can be activated very easily. And with his 8 power, he can become part of a win-3-rounds strategy more easily than any of the other Skeelz nukes.
Better yet, it's a pain for your opponent when you draw Manfred and Jay together, especially with an easy opener like Sasha.
