That's a first, you switch Surf to Hydro Pump? Usually it's the other way around, lol
Actually yes, before I had Hydro Pump, but because it has 0% accuracy, I changed it to Surf.
Now that I think of this match, I would have won 1-0 if I had Hydro Pump instead of Surf. His Terrakion and Landorus both would have been OHKO'ed by Hydro Pump. And my opponent/TC/Tourney organizer knows that :p
But of course, it is nearly impossible to hut 2 Hydro Pumps in a row.
