Strategy
This deck primarily relies on the combination of two Lv. X's : Giratina and Gengar. The mix of spread damage, level-up prevention (especially for certain SP's), attack prevention and card loss for your opponent can prove to be an interesting offense. I also threw in some extra poke's and other cards to help get counters on and set up my poke's and energy quickly.
