She took his power and held her own for a page or two but couldn't hold on to the power. The only other person who she's been shown having difficulty holding onto and using the power of was Dr Occult. Though that IMHO is more due to his magic immunity. The issue of Secret Six where she took Occult's power she couldn't control a teleport and had no idea where she was. She had a spat about working out how to use Occult's power in seconds but that had never been an issue before.
Absorbing man
Amazingman II
Zoom (can't believe he's listed as Herald on the Tiers list, but I'll take it)
Flash
Both Absorbing man and Amazingman copy Zoom's power at the onset of the battle which allows them to run rings around whoever.
AM drains the enemy team members one at a time (the same way he drained Overmaster who was a Galactus rip off) while the two of the other three blitz the shite out of them with IMP's and the third keeps the rest of the opposition off AM.
