Looker's is definitely the way to go. Draw as little as possible, and then use Scale Blow for a single Water Energy and a DCE. Hayadern, 110 with Expert Belt right there. Unfortunately, you have Luxray GL LV.X to worry about, and the fact that he has the SP Engine on his side, and that he needs one turn to hit you with 80 damage if he's got the the Energy Gain, and that it's an OHKO if you don't have an Expert Belt and he Crobat G drops you.
