Fairly far into the game.
Repping Delphox, Doublade, Floette, Tyrantrum, Sliggoo, and Pangoro.
Delphox for a starter is ridiculous imo. One of the most powerful starters I've ever had. Honestly makes most story fights trivial with a single flamethrower laying waste to everything.
My Pyroar does the same thing with Hyper Voice and Flamethrower. Three fourths of the time or so it faints pokemon those moves are normal on in one hit.
I kind of find it annoying how, despite all the streamlining and quality of life, changes they made you still are forced to carry around a Pokemon dedicated to HM's.
I find it more annoying that you can't delete HMs whenever you want now. I taught my Pyroar strength because I thought I could get rid of it whenever but I can't. And the move deleter is after the 6th gym.
Delphox tends to kill EVERYTHING in one hit. ;) Of course mine is slightly over leveled, but I calculated some of his base stats at 50, and found that he is closer to 120 or so for special attack. That kind of makes him a prime damage dealer in general anyways, but his typing just makes it even more so pertinent as if fire don't work somehow, the psychic sure as hell will.
I'm expecting some sun coverage in the metagame based on it. Should be one to watch out for I would think. Then again I'm just saying that without too much analysis in it.
