Interesting... Free retreat, status immune, instant knockout with Ariados's ability. I actually had some success with Doublade and Ariados as a Rogue deck at one time, but the issue for this one will be the development of the strategy. I'm finding Break Pokemon pretty difficult do get out quickly...
Fortunately, it could be easier to do for this break card, as we have Winona to quickly get the Ratties out. Yveltal for Acceleration and Night March handling, Assault Vests and Head Ringers for protection, and you have an interesting strategy to try out!
