The animation for Delta Charizard's Mega Evolution seems to take longer than it used to. I don't know if this is intended or not.
Same with the mega flygon one!
Same thing happened with my Delta Venasaur and my friends Delta Charizard. I think it's part of the game.
Same with my Eevee, and opposing megas.
