Well I know one way on how to pretty much get a guranteed win. You need a Ventus Hades and the Ventus trap scorpion on the Hades Character card. Change hades to Pyrus with the trap so you get +420G from ONE card!
Well it's an OK team, but in a tournament G-Power Boosts won't save you, so I think it's better to have Very High G-Ones and use cards like shadow vortex and Shadow lash so they get no Gate bonus, and you win by a landslide.
Well, V's Theory on how to use Maxus Helios is pretty good.It's just that you should only choose ONE G-Power and the whole thing gets Gate Bonuses depending on the attributes of all the bakugan that make it up. Like, if you have a Maxus Helios with all 6 attributes, you get 6 gate bonuses.
I'm pretty good at everything but Pyrus and Sub-Terra, Have a KILLER Ventus Strategy and I'm Ok at Haos. When it comes to aquos, well, I'm Ok but dont have an Aquos Strategy Yet… But I will soon make one.
More good ones are Anything like the Light Wind, Dark wind, fire wind, and Water Wind, Rainbow Prism, and any of the Freedom cards if you are using a bronze attack and have 2 cards in your used pile.
