Ok, Kelsier and Vin and Wax have enough of the eight basic metals to last through the battle. Neither has Atium, and Surgebinders have enough Stormlight to last through the battle.
Now, I would like to address the question of Wax V Kelsier, because me and my friend think Wax would win. Wax has the ability, assuming he has enough weight stored up, to use steel in a way that is far more powerful than Kelsier's Steelpush/Ironpull. So, in theory, Wax could push Kelsier through a building or something. Secondly, Wax is simply better at steel than Kelsier ever was. He has enough control to create a steel bubble without affecting his weapons or bullets. Thirdly, Wax can literally fly, if he didn't want him to, Kelsier couldn't touch him, and finally, Wax is just a better fighter than Kelsier. I mean, Kelsier had trouble with six hazekillers. Wax has taken down twenty men on his own.
