man, this gauntlet is just sad. nearly all the X villians have been downgraded and depowered since their heyday. Jugs, Apocalypse, and Sinister USED to be team wreckers- The current versions would be one shotted by a GL with little effort.
That leaves magneto, who would use the "iron in the blood" trick to cause a stroke in the opposing team, killing them all on his own.
Magneto FTW.
(ok, not really...green lanterns 10/10)
