Hey guys so this is my very first NU team as well as the very first team I have made in general so it might have a a lot of flaws on it. I have been using this team for about a week and I get some wins but also some loses.

Typhlosion is the newest member of the team and he was replaced by prinplup because there were battles were there would be a grass type pokemon like lilignant and I would not have anything to threaten it with and prinplup would die on me easily. Well anyways Typhlosion is my main sweeper and he does a pretty good job at it. I decided to use flamethrower instead of fire blast becuase I wanted to rely more on the accuracy even though I was loosing power. Ability: Blaze

Well thats the team I have at the moment. One other thing I think I should add is that during the beginning of a battle I tend to do really good but later on in the match the team loses momentum and I quickly lose mons and sometimes I lose just because I did not have a pokemon that could of done any damage. I'm not sure if thats cuz of the team or becuase of how I play lol. Thanks for reading and any advice would be really helpful.
