I was down to my last pokemon Ampharos...and Clair was down to her last pokemon Kingdra.
So kingdra used Dragon Pulse, and Ampharos was left with just 4hp......at this point Kingdra still had a good chuck of it's hp left and I was pretty much already planning where I was going to train to get stronger :p
But then....Ampharos used Discharge......critical hit....Kingdra fainted.
I'm so happy right now, critical hits like that are so satisfying <3
