I'm probably the only person that has actually used Monferno in this thread. First, I agree with everyone saying that the Endeavor set is not even good at what it is supposed to. Anf for any other Monferno set, that is what I used back in January, it has no real benefit for using it over other great Fighting-types in the tier like Gurdurr or Emboar that are overall insanely more useful for what they are needed (Priority in Gurdurr's case, Nuking the Opponent with insanly powerful attacks in Emboar's case). Monferno's speed is not enough to save him from being outclassed at everything it can do, and even suck at the only thing it can possibly do in theory. As for U-Turn, there are superior options that have way more offensive presence than Monferno or forces more switches than what Monferno will ever do such as Cinccino and Braviary.
