[RATE MY TEAM] Please rate this team (Not really mine but I wanna improve it)

[Kapperin0]

Firstly, this team is not of my creation and I hope the original creator of it let's me use it.I am really interested in this team and I'd like to use it myself and do some tweaks on it for competitive play. Ive only recently started playing seriously and it'd be nice to have a good team to play with like Whimsigar cuz it seems so interesting! I really dont like the fact of using thundurus or metagross. If there are good subs please let me know.  All credit goes to the writer and creator of this article: https://vgcwithhats.com/2015/03/23/the-d...-analysis/
