Okay, this story kind of feels like Discord and Celestia are playing a badly-acted role-playing game. I mean, the two of them don't quite feel in character. 
At the same time, it's oddly funny how seriously they're taking getting pelted by pies. 
Okay, the reference and the board game scene were funny.
Discord and Celestia still feel a little out of character. Hmm, do you ship Dislestia by any chance? This story feels like a weird Dislestia shipfic. 
So, the Mane Six used the Elements of Harmony to create a giant pie to raze Discord's army with?
Oh my gosh! That's hilarious! 
Too bad that Discord and the changelings all got turned to stone. 
Okay, I looked up "Dr. Tezla," and the first thing that came up was (dramatic pause) Hot Wheels.
What? 
Okay, this story feels like what happens when a bunch of little kids get together and dump all their toys out in the living room floor. Is that the feeling that you were going for? It's not a bad thing. I mean, it's a little nonsensical but fun.
