Switch your 0-retreat Serperior VSTARs in and out of the active until they all have damage on them, and then Cheryl! Stop your opponents from gusting up your damaged VSTARs with Leafy Camo Poncho, and draw cards with Research and Radiant Venusaur!
Suggestions welcome - please do comment with improvements (especially if they involve teching for Giratina VSTAR, which is a real pain for this deck!)
