Round 1:
Vin vs. Raoden
To be fair, you'd have to let Raoden have as much time to get used to the AonDor as Vin has had to get used to Allomancy. Just seeing the skill that he has after the little time he's had it in the book, I'd say if you give him even one more year, he'd be skilled enough to take Vin down. He's already getting pretty fast at drawing the Aons, and he'll only get faster with time. Plus, I can see him getting to the point of being able to draw two Aons at the same time....Doesn't matter how fast Vin is, she wouldn't be able to counter that....She's gone.
Round 2:
Kelsier vs. Dilaf
Kel wins. There's really no contest to this one. Sure, Dilaf is freaking strong, but he doesn't stand a chance against just iron/steel. That's not even taking into account pewter and tin, not that tin would really be able to do a whole lot, but still. Kel whoops Dilaf.
Round 3:
Sazed vs. Susebron
Sazed puts up a VERY good fight, but he just can't work his away around all the Awakened objects and Lifeless that Seb has at his disposal to face Seb head-on. Seb wins.
Round 4:
Vasher vs. The Lord Ruler
Vasher can't even beat Denth in a fair fight (notice I said FAIR....I won't say what's unfair so as to avoid spoilers...). Even if he pulled what he did to Denth on the TLR, he would still lose. TLR would be able to heal from whatever injury Vasher inflicts upon him, he'd be able to take down whatever Awakened forces Vasher uses, and he's really not all that evil of a person, regardless of what Vin thinks, so not even Nightblood would work on him. TLR takes the win.
Round 5:
Spook vs. Vivena
Doing the same thing with this fight as with Vin vs Raoden, Viv has more time to learn. Not only this, but she's been training under Denth and Vasher, both of whom have extensive knowledge of Awakening. Yeah, Spook's a savant. As we saw in HoA, he can do a LOT. But Tin isn't going to help him with Lifeless....And yes, I can see Viv getting around to Awakening a Lifeless or two sometime....Granted it would take her a while to get to that point, but it will happen, eventually. And when it does, Spook's toast.
Round 6:
Denth vs. Marsh
Denth is killed less than a minute in to the fight. Yes, he's good. But he stands no chance against a super-powered Inquisitor like Marsh...No chance at all.
Round 7:
Raoden vs Kel
Again, Raoden has had time to develop his skill. Not more time than he had with Vin, but I think it's safe to say that Vin would beat Kel in a fight, and therefore, if Raoden beats Vin, he should be able to beat Kel. Kel uses his skill with steel/iron finely, but Raoden turns them all the metal to feathers with one Aon he draws in his left hand, while drawing an energy Aon in his right hand.....Kel dies.
Round 8:
Seb vs TLR
Seb puts up a marvelous fight with all his Lifeless and the other Awakened objects. It doesn't take TLR all that long to get around them. TLR controlled Koloss, which I'm sure were MANY times more difficult to kill than Lifeless. And since there's really only so much you can do with Awakening--since there are only so many viable commands regardless of how much Breath one holds--as opposed to the combo of Allomancy and Feruchemy, the combo takes the fight. TLR wins.
Round 9:
Viv vs Marsh
Doesn't matter how much training Viv gets. She's not beating Marsh. Marsh has already faced one Awakener, and a pretty good one at that, plus a really good fighter on top of being an Awakener. Viv's not a fighter. She may be an Awakener by this point in time, and she may know a bit of how to fight, but she's nowhere near Denth's ability. Anything she throws at Marsh, he counters. He's seen it before, plus more. Nothing is new. She dies much faster than Denth did, which is really only fair.
Round 10:
Raoden vs TLR
Raoden's seen and beaten 2 Mistborn, easily. He's ready for more of a challenge. He sees TLR's Feruchemical abilities--like the speed and the healing and the strength even more than the Mistborn--and he's not QUITE sure what to make of it, but he uses his brain, and the Aons to the best of his ability. Keeping up with his "left hand metal-feather-turner, right-hand offense" thing he had going on for him during Kel's fight, he's able to fight off everything TLR sends at him, plus give a few injuries in return. Granted, those injuries heal up fast, but hey, it's using up a good portion of TLR's stores--both of pewter and of Feruchemy. Eventually, Raoden decides to try something new, and adds a modifier onto one of the metal-feather-turner Aons, making it so the metal TLR is wearing also changes....And thus, TLR is beaten.
Round 11:
Marsh vs Raoden
After having JUST beaten TLR, fighting Marsh, although another invigorating fight, is nothing new to our Elantrian friend. He notices right off the bat that Marsh is a little different than TLR. I mean, for one thing, TLR didn't have a metal spike sticking out of one his eyes, and a hole where the other eye should be. Plus, Marsh isn't wearing any metal....well. Other than the spike, that is. But still. Raoden figures out a modifier to put on his trustworthy feather Aon (I can't remember which Aon it is that makes an Elantrian able to shape-shift objects, and I don't have my book, so that's why I keep referring to it as the metal-feather-turner...It's not really. It can do more than just that, but that's all that really matters within the confines of these fights...or at least that's all that I choose to use it for...) that will change that lone spike in Marsh's head to a feather....And as we saw in HoA, when the Inquisitors lose both of those spikes, they become a little dead....
And thus, our Elantrian friend takes the trophy....whatever it may be.
