Flutter Mane is a Ghost & Fairy type, is the past paradox of Misdreavus, and has a very cool design, alongside a pretty nice shiny. I would say I prefer design of Flutter Mane to original Misdreavus by a good margin, although I love Misdreavus' design as well. However, when it comes to battles, Flutter Mane is probably the best paradox to use both in game and competitively, with it having great stats, a great ability in Protosynthesis to allow itself to boost up its great stats even further, and a very good movepool. This was in a similar boat to Houndstone and Palafin where it got banned to ubers pretty quickly because of how powerful it was. I absolutely adore Flutter Mane, but it's definitely not my most favorite of the paldea paradox pokemon, and I was extremely close to taking it out at 12th/11th over putting it in my top 10, which it's because of those reasons that I had to take out this prehistoric ghost for 10th.
