In that story arc she saved the universe, cut and clear explained, as for saved the day, it's a common catchphrase, you very well know that, so let's not pretend that we don't know notions like this.
Of course Wanda is with her, read the scans, it was because of Wanda why the universe would have been gone, since Wanda's powers interacted with machine's energies which would have created a space/time disruption of universe literally annihilating the known universe, frankly Domino's probability powers changed that.

As far as Longshot goes remember when his soul was fading away.
He learned a lot about illusion and could find even footing with Domino anyhow.
Then it would be a matter of how many darts he can throw at Domino sorta like the knife thrower in the Circus.
I don't understand what you are trying to say in regards to illusion part, clarify that part, if you can.
He won't find even footing with Domino, she is much more skilled and more ruthless fighter.
Sure, he can throw all "darts" that he wants, except all of them would miss, his luck power malfuctions when meeting other probability users, i already showed that with scans, meanwhile Domino would be fine and her powers + her skill + her reflexes would allow her to dodge anything Longshot can throw.

Longshots darts cut through anything. If he has Domino anywhere near anything he can toss a dart and kill the person with illusion like the fake throwing knives in a circus.
Again, you are fogetting that A. Longshot's succesfull hits come from his LUCK POWER, but he doesn't have luck here, i already explained that aspect countless times, and B. Domino's speed + skills + reflexes + her luck power would make her dodge any attack Longshot can throw.
So let's stop going through circles, there are no constructive arguments brought up here, only circling.
