Here's an alternate way to get Wiscash to go first:
EVs: 128 Def, 128 Sp Def, 100 HP, 152 Sp Atk
-Surf / Scald
-HP Dragon / Future Sight
The idea is to start with either Mud Shot or Icy wind, which together have very good coverage. You'll have to take a hit before doing this, because this Wiscash isn't fast off of the bat, but on the second turn, you'll be able to go first and finish the foe off. I don't know why I threw in Future Sight, I just like it for its ability to provide come-from-behind victories.
