This is one of those fights that sounds like there's a lot going on, and, well, there is, but its actually pretty simple in execution. There's lots of abilities you need to know about, but dealing with them ends up being pretty straight forward. Lets get on with it.
Abilities
Immediately upon starting the encounter, Ultraxion will pull the entire raid into the Twilight realm where he's at his most powerful. However, this also grants everyone a special, encounter-specific ability called Heroic Will. By default, this appears as a small icon in the middle of your screen, but if your UI has it hidden, you can manually keybind it under Extra Action Button 1. Anyway, when you use Heroic Will, you'll leave the Twilight realm for 5 seconds. That's important for dealing with two of his other abilities.
The first of these is Hour of Twilight. When Ultraxion casts this, everyone in the Twilight realm takes 300,000 unresistable Shadow damage. What's worse is that 3 players have to stay behind and get hit by it, or Ultraxion kills Thrall and the Dragon Aspects and everything on Azeroth dies -- starting with your raid group. We'll talk about avoiding that particularly unpleasant situation in a bit.
The other ability you'll need Heroic Will for is called Fading Light. He'll occasionally cast this on the tank and two other raid members. When the debuff fades, if you're in the Twilight Realm, you die. Again, we'll talk about that a little later.
Ultraxion has an aura called Unstable Monstrosity. This causes him to do a large amount of shadow damage split between everyone in the twilight realm. He starts out casting this every 6 seconds, but as time goes on, he casts it more and more frequently. For some reason, this also means he can't parry, so there's that at least.
If, for some reason, there's no one in melee range, he'll cast Twilight Burst. This does a rapidly increasing amount of shadow damage to the entire raid. Fortunately, there really isn't any reason to move, so if you're seeing this, you're doing something wrong.
Last up for Ultraxion, we have Twilight Eruption. After 6 minutes, he explodes, instantly wiping the raid. That means Ultraxion has a hard, 6-minute enrage timer.
Now, Thrall and the Aspects have their hands full with the Dragon Soul, but they'll still help out when they can by casting various buffs. At the start of the fight, Thrall will cast Last Defender of Azeroth on the tanks, which lowers the cooldowns of their major defensive abilities, such as Shield Wall, by 50%, and doubles their duration.
Alextrasa, Kalecgos, and Ysera will summon various crystals that healers can click to gain a specific buff. Two of each crystal will spawn. The red crystals spawn about a minute and a half into the fight, their buff will increase all healing done by 100%. A minute later, the green crystals spawn, and will cause all of your healing spells to heal the same amount again, split across the entire raid -- basically an AOE healing buff. The blue crystals spawn a minute after the green and will reduce the mana cost of all spells by 75% while increasing spell haste by 100%. Once a healer has activated a crystal, they have that buff for the rest of the fight and cannot take a different buff.
Finally, 5 minutes into the fight -- so one minute before the enrage timer -- Nozdormu will buff the entire raid with Timeloop. With this active, if something would kill you, you get healed to full instead, but you lose the buff when that happens. This is especially handy since this is the point where the raid damage starts to get out of control.
Strategy
Okay, now that we've gotten all that out of the way, lets talk about how to kill him. Like I said, it's pretty straightforward. Everyone should stand grouped up directly in front of him, just inside of melee range.
When he uses Fading Light, tanks should swap, and the three people affected by Fading Light should use Heroic Will when it's just about to expire to keep from dying.
When he casts Hour of Twilight, everyone but the two tanks and one other player should use Heroic Will to escape it. The three that stay behind will need to use some form of survival cooldown to stay alive. Tanks should easily have defensive cooldowns available thanks to Last Defender of Azeroth. The third person can be anyone with a substantial survival cooldown like Dispersion, a self-save talent such as Cheat Death or Cauterize, or even an external cooldown such as Guardian Spirit. He'll cast Hour of Twilight every 45 seconds, so make sure you assign things appropriately. If you're using 2-minute cooldowns, that means you'll need a 3-person rotation.
As for the healer buffs, remember that each healer can only have one crystal, so just assign them ahead of time based on what classes you have and what their healing assignments are. Due to the nature of the buffs, there isn't a real specific priority for who should get what buff. They all roughly work out to be a 100% increase in healing done in their own little ways.
This is as close as it gets these days to a straight-up numbers fight. Just stand still and burn as hard as you can. As long as you can handle his fairly simple mechanics, it's mostly just a question of whether or not you've got the raw throughput that it takes to bring him down.
