I was batteling a friend on ds. It started with that I sent out my Jolteon and he his Ferrothorn. I used Curse twice and he used leech seed and one power whip miss. Then he used Then he used Explosion before my Jolteon and crited.
The question is how the heck did he be faster??
And I'm 100% sure that I havent cheated
266 / 2 = 133.
Max Speed Ferrothorn: 152
If your Jolteon has 302 Speed or less, and Ferrothorn has Max Speed, Ferro actually outspeeds.
Also, maybe Trick Room was up?
