How is a Diggersby able to outspeed my Greninja?

Question

My Greninja is trained to have max speed and a Diggersby attacked my first. There was no tailwind, or other moves used that affect speed.

Comments

probably choice scarf

What move did he use?

Answer 1

Because Diggersby is god.

Lol jks, Cwegz is right. Max speed Greninja is 377
Max Speed Diggersby with Choice Scarf is 420.

You just got outswagged.
That or he used Quick Attack (Which is priority), or a move like Tailwind or Sticky Web was in play. And you just didn't notice it.
