No thats BS this is just like that "Stealin" thing. You should only be able to right after a gate card is set. Just like Aquos should only work at the beginning of a battle and not only that but you need an Aquos monster at the begginning of that battle.
V did that in one of his brawls, and you can't do it when your playing in real life, but for online brawling you can.
