I don't love Wieg's writeup. Just sealing the ubers off from the battlefield, so the outcome of the battle doesn't matter? I thought that was kind of lame, plus it's not totally clear to me how they were sealed off. (Truth be told I don't really remember how people got in and out of those various environments in Exiles -- was there a door they walked through?)
But I'm sure Wieg would have done more if he had an actual opponent, so I can't be too critical. It's certainly enough to get the win against a no-show. I vote Chaos&Order.

In the other match both are good writeups, although there are some specific points in each I disagree with. So it's not an easy decision. Harl had Flash attack by adding speed to Turtle's brain. Harl says Turtle can't absorb his own speed. I'm not so sure he couldn't absorb the extra speed as it was being added. In Turtle's case, absorbing speed doesn't seem to mean making himself faster (in which case taking speed from yourself to give to yourself speed would make no sense). It just seems to mean taking speed away to store and give back later. Still, I could see that fight going either way.
A bigger issue is Quasar. I somewhat disagree with both Nightwing and Harl's interpretations. Nightwing says it's fine to give yourself tuber powers, so long as you don't use them. I don't agree with that. By that reasoning, we could allow a tuber like Galactus so long as he willingly limits himself to only using uber-level power. Really, characters are ranked tuber based on what they're capable of doing. Not using the power doesn't change that he has it.
But I also disagree with Harl. He has Replicant steal Quasar's power, and then either disappear (from going over the tuber bar) or explode (from not being able to handle the power). I don't see the tuber bar working that way. If something would make you tuber you just can't do it. Saying you do it anyway and lose by some kind of forfiture doesn't make sense to me.
So if Replicant + Quasar is a guy with tuber level power (which I think it is), then Replicant just can't steal Quasar's power. That invalidates both Nightwing's way of beating Quasar, and Harl's way of beating Replicant. So in that sense, it all evens out.
But Harl did something else I disagree with. He amped Animal Man to a higher weight class based on the opening created by Quasar's depowering. I don't think that's allowed. If you have an open roster spot to start with, you can amp a guy up. Maybe you could de-power one guy in prep-time to make room to amp a guy up. But amping a guy up because another guy gets depowered in the battle makes no more sense than amping a guy up because your uber has been killed. Once the battle starts, your characters are ranked whatever they're ranked regardless of what happens to them. Plus, if Replicant couldn't steal Quasar's power due to the tuber bar, that slot would never be open anyway.
So I thought Harl's writeup overused the whole Replicant depowering Quasar thing more than Nightwing's. And since I found that suspect, and in other ways I thought they were pretty even, I'll vote for Heroes of the New Age
