I am using Gallade SW. I get the Gallade running and do 60 and then 20 for each prize card I flip over. When all the prize cards are flipped up I use Azelf to look all again (but it doesn't really matter). I pick a pokemon then I flip them all over again to do more damage with Gallade again...I use 2 Azelfs.
Does that work? I dunno, seems like the prizes would stay flipped over... If it does work, however, I would run more Azelf than 2.. Maybe like 3 or even 4.
