For me, VILANTOR Bronze, because it directly counters the Ventus strategy.
I've heard this a couple of times. How?
Its Aquos effect for the Gear is just about if not exactly the same as the current card "Ventus 2"
So how does it counter? If it does the same thing, that's not countering it.
It doesn't do the same thing as the Ventus Ability. Ventus lets you switch the current Gate with one from your used pile. Ventus 2 Ability lets you switch the current Gate from your opponent's used pile. So essentially it could be like this, they're in a tight spot and losing on your gate, so they decide to use Ventus. Whooosh, now their Low Bridge or Needle's Eye whatever is now the current gate and it looks like they're going to win. But wait, you activate Ventus 2, and switch it right back! And they lose!
That's right. It not only nulls the effect, but gives you the VILANTOR bonus as well.
