something that you also have to realize is that you have to play down a baby balloon which basically tells your opponent, "Hey! I run balloon, I run balloon, I run ballon!!!" They will obviously catcher KO it before you can get it setup. And even if you can get multiple going it is very easy for them to KO you. And along with that, balloon does not do well against decks like Kyurem/Deoxy/Keldeo which runs very few special energies. Overall I would say that the card is completely pointless and the space can be used for many other useful cards.
