Reason for the name was that it came after some time trying to make a nice deck working with Jean Grey. It was based on another one I had after some adjusts I made just when Elsa Season started. It made me reach Infinite from 70 in 7 hours (03/Oct/2023), being one of the first 41 to make it as that was my rank when I did. It keep working fine after that, though I made some changes also sometimes, specially after Forge change.
The way it works is easy, you try play Elsa and fill 3 cards in one location. If you can make it with Jean Grey you will be forcing your rival to play one location and wil play yourself there your moving cards just so they leave location buffed by Elsa. Other option is Forge/Brood and have there the buff machine (I would suggest to avoid playing unbuffed Brood alone, except necessary, like due to Storm, Kyln... or anything similar). It also has some good possibilities for last turn, if you're worried about Alioth a moving buffed Vision works great against it, you also have your own Alitoh (specially good if you have Jean Grey and he has a free slot there) and if you need some help at your sides but have played Jean, Doctor Doom will be useful too. Gamora also works great with Jean Grey and could be buffed both by that and Elsa.
It's quite flexible and my only complain is that many times you don't end up playing Kitty Pryde on 6, so I usually don't buffed her and instead use it to help buff other cards while letting the spot free for next turn and buff Angela. An alternative would be, specially if you don't have Alioth, change Alioth for Taskmaster and then you can more likely buff Kitty all you want to play her as a last combo.
