I thought of a tottaly rouge idea. Have raikou and enti legend and have igglybuff and cleffa in a deck and also have the card twins and have rescue energys and rainbow energys and some indigo plateau's in a deck. The only problem i see with this deck is donphan prime. Well this idea can be very easy to set up because of the card twins and pokemon communcation and all the pokemon here have free retreat so pokemon catcher wont hurt this deck much. And you can get raikou and enti back in your hand with the card seeker and play it right back down. At the begining of the match you stall them with igglybuff or cleffa and when one is knocked with that can be easy to do you can play the card twins and set up raikou and enti.
