I am an aquos brawler. I will post some of my strategies.
I normally use aquos taylean 760, Fencer 700, fear ripper 500.
My cards are low bridge, river gate and construction gate. My abilities are bright eyes, rain of shadows, and water wind.
First i start with low bridge, and put my fear ripper on it. I am sure to win unless my opponent uses an aquos bakugan with lower than 500 g power, or a haos with less than 450 g power, and so on.... If my opponent puts a bakugan on his own gate card, i set river or construction gate, roll my taylean and use water wind. i can move any bakugan to any gate card. If the enemy has more than 500, i put it on my low bridge with fear ripper. then i am sure to win. If they attack my taylean, the card will give me alot of power but it wont give the opponent very much. I will continue later. please post what you think.
