If this is posted I think it would go under Single card Tips then under combos.  OK here is my strategy. But first here is the cards translation:
 
Team Rockets Explosive GYM:
Whenever a player plays a basic pokemon, that player flips a coin.  If tails, this card does 20 damage to that pokemon.
 
First lets say your hand is this:
 
1x movie pikachu
2x Bill
2x scyther
2x lightning NRG
 
First you put Scyther as active and bench Pika and the other Scyther.  Your opponent has 3x Rattata.  Let's say you call heads and it was heads.  You draw its another lightning NRG.  You use bill you pick up a Dark Raichu and Double colorless NRG.  For this ex. you attach the energy to the pika.  Let him go.  he attaches energy and bites for 20.  You draw and its an Nrg removal. you use it on Rattata.  you attach the other lightning energy to pika and use bill. You draw another  lightning and a Electabuzz.  You bench the Buzz.  You are done now.  He picks up and passes.  You pick up and it's Team Rocket's Explosive Gym. You use it and since its a stadium card it stays in play the whole game.  Then attach the last Lightning energy to pika and evolve him to our friend Dark Raichu.  You are done.  He picks up and puts both his Rattata on his bench.  He flips the coin and it is tails for both of his Rattatas.  20 damage to each benched rattata.  He passes.  Your turn you retreat the Scy and promote Raichu.  Use surprise thunder on the rattata he is now fainted and you still aren't done.  You have to flip a coin to see if  his bench receives any damage.  You flip its heads.  Then flip again and its tails.  His benched pokemon receive 10 damage. Since rattatas have 30 Hp and they were hurt from the stadium card they had 10 left.  Guess what you just killed all his pokes in 1 shot.
 
Overall:
What you want is Dark Raichu to come out early and TREG to come out a little after that. Then you will be hopefully be killing pokes left and right.
 
Remember this was just a Demo battle anyways.
