Well the stratgie here is to use crobat's attack server poison and then retreat crobat for gengar prime then use one of gengars attacks if they get knocked out by poison they go in to the lost zone because of gengars poke body. You can also snipe with crobat then retreat crobat for gengar then snipe with gengar. I can also use one of crobats attack's then the next turn switch a energy off of crobat with mismaguis's poke power. And i can lay down jirachi and then move the energy off of jirachi. Here is my deck list.
