I don't think that the Psi's would be able to overpower Sentinel
which is who wins it for team Top Tier. I also don't see Onslaught being much help in this battle except for dealing with Cyborg and even then there is a chance that he could get around that.

Only possibly against Cyborg Superman and even that has been debated, and I don't think that Alan's constructs run the same way as other Lanterns so the possiblity of him overriding control due the whole "light" thing is out. But this is just my opinion and I could be persuaded to think otherwise. But personally I Scott is too powerful to be here and gives the Top Tiers the win because of it.
