I don't know why you're so determined to make the point that you think the Ultra Beasts are bad. Like many others here have said, the whole set hasn't even been revealed...
All we know outside of the Ultra Beasts that have been released is that there is a new kind of energy being released with this set. As for what that new energy does, no one knows yet, but I'm fairly confident that it'll be related to the Ultra Beasts. How about we wait and see the whole set and see exactly what kind of Support Ultra Beasts get before jumping to conclusions.
