His strategy is to use Pichu/Cleffa/Tropical Beach to quickly set up Vileplume and Reuniclus, hopefully turn 2. After that select the card that works best against the opponent (Donphan Prime/Zekrom/SEL) and manipulate damage counters to elimate the opponent while not losing any more prizes. He expects to lose a prize or two because of babies/basics, which is why he has such a heavy inclusion of twins. That's how I played it in my testing anyway, and it worked very well.
