I've played Giratina EX with Vilplume a lot since the release of Ancient Origins. It's so much fun to see the opponent get another card in their hand each turn that they can't use
The deck really shines if you get your set-up right during the first turns. Though this may be difficult at times. Charging Giratina EX with Double Dragon / Colorless Energy is an easy task without means to discard the special energy.
It's also nice to see another player that loves the new Weavile card. It has so many uses. I replace Zoroark with Weavile as the retreating Pokémon because it can move Float Stone to any Pokémon on your side of the field. I would recommend replacing Manaphy EX with Float Stone for this reason. They both relie on abilities either way. That would be one less easy to K.O. Pokemon EX on your bench. Also you don't have to attach a water energy to Hoopa or Shaymin EX in case they get Lysandre'd. I like healing decks, so I may try this deck idea out if you don't mind. Good article!
