The fastest way to finish a game would be Plasma Lugia turbo though it would be incredibly hard to set up and you'd have to have your opponent playing the worse EXes like Mew and Jirachi with under 130 health. You could knock out for 3 prizes, then knock out turn 2 for all 6, but you'd need to set up 4 energies turn 1 and make it so you go second so you can attack. Shit like that is incredibly specific and impossible to ever pull off, you have a much better chance of just killing your opponent's only Pokemon and them not having anything on the bench for you to win right there.
