Going all out for this one as I plan on actually adding personal commentary on how this fight could go down.
So, the JSA against the Uncanny X-Men.
Right off the bat, the X-Men should appear here as the underdogs power-wise compared to the big guns of the JSA.
How much of an underdog in this fight?
Here's the JSA roster for this one:
1). Green Lantern
2). Dr. Fate
3). The Flash
7). The Spectre
8). Dr. Midnight
10). The Atom
And now here's the X-Men roster:
11). The Beast
Now as you can see, I made it fair to both teams by having the same number of embers per team. And while I was going to originally stop at 7, 8 at the most, I found myself wanting to include all the main JSA members, thus forcing the member number to grow to 11.
At first look, it kind of looks even in terms of overall power between the two, but to me, I see someone like the Spectre to be capable of taking on the entire X-Men roster and winning pretty handily. Hey, he's the Spectre, tell me you don't see him easily tearing through the mutants like a hot knife through soft butter. And that's with two world-class telepaths and the power of the Phoenix Force.
Skipping coming up with a reason why these two would fight, let's just get to the fight itself, shall we?
And fight they do, both teams going hot and heavy, trading fierce blow for fierce blow.
For me, it all comes down to the main big guns on both sides. For the JSA, it's Green Lantern, Dr. Fate, Starman, the Flash, and of course, the Spectre.
For the X-Men, it's the Phoenix, Rogue, Cyclops, Wolverine and Storm.
In my scenario, that's pretty much who's left after a long and very drawn out battle.
Let's say for arguments' sake, Cyclops, with an assist, takes out the Flash.
Starman and Storm take each other out.
The Phoenix either goes after the Spectre, or fights both Green Lantern and Dr. Fate.
Let's say Phoenix does just this, who with the help of a barely conscious Psylocke or Prof. X via long-distance, is able to mentally overwhelm Green Lantern's willpower, and posses him, causing him to attack Dr. Fate.
The Spectre easily takes out the rest of the X-Men, leaving on the Phoenix to deal with.
The Phoenix has her hands busy with Dr. Fate, even with an assist from Xavier.
Even if I was being really generous here, and took out Dr. Fate, that still leaves a very powerful and pissed off Spectre.
The two go at it like never before, oblivious to the massive surge of power and energy their battle is causing, and how much it's quickly enveloping the Earth.
Earth is pretty much an afterthought to the two demigods, as they attack each other with everything they have.
Now this could go either way. One hand, the Spectre eventually overpowers and takes out the incredible force that is the Phoenix, since he's God's personal spirit of Vengeance.
He's hampered/restricted power-wise due to receiving his powers directly from God, and maybe God isn't interested enough to let the Spectre go full out.
They both take each other out.
Either way, for me, it comes down to these two in the end, no matter the outcome.
The X-Men better be glad I didn't go full on traditional, and allow the Golden Age versions of Superman, Batman and Wonder Woman join their follow JSA teammates or else this fight would've been a whole hell of a lot one-sided.
The Uncanny X-Men
Who wins and why?
