Fun fact: if you play this as printed, you can add in any modular set with environment cards in it and it will break the scenario. So my suggestion is to use a house rule that this main scheme only discards environments from the Absorbing Man encounter set and only does so if the new environment is also from the Absorbing Man encounter set.
Her response is handy for retrieving your Ruby Quartz Visor, if you had to discard it for some reason. It's also a great feeling when you are trying to close out a game, and can use her fetch your single copy of Full Blast. I had a game once end by me exhausting Cyclops to attack, playing Phoenix, fetching Full Blast, then re-readying Cyclops because I had Utopia in play, then playing Full Blast to end the game.
Is he a nemesis minion?
i mean usually they have this in text "(Thor's nemesis minion.)"
and if he is not - how it work with new FACE THE PAST and shadow of the past?

In a deck with reliable Confuse, like Spider-Man (Miles) or Gambit, you'll probably be able to play Spider-Woman for 2 with a confused villain a lot of the time. To get beyond that you'll have to confuse minions, which means leaving minions in play in order to confuse them, and confusing the villain is a lot more valuable than confusing minions, so you might be able to play her for 1 on a lucky day but 0 is highly unlikely. Outside of a deck like that, Spider-Woman is definitely not worth it, as there are a lot of better 3-cost allies in both Justice and Basic.
But the thing is, even if you do get to play her for 2, she doesn't do anything special besides thwarting twice (or attacking once) and then defending, so even then I don't really think Spider-Woman is worth considering. Even in Web-Warrior decks where you care about Web-Warriors leaving play, almost all of the other Web-Warrior allies cost 3 or less, and most of them do something when they enter or leave play beyond simply attacking/thwarting and defending. Happy to be proven wrong though.
During my first couple of times playing Magik I missed that her unique ability is 'once per phase' rather than 'once per round'. This means that she can use her ability to play Magic Barrier (for free) off the top of her deck during the Villain phase, and then play another card with that ability during the Hero phase.
With Limbo, Stepping Discs, and her alter-ego ability, it is very easy to have a Magic Barrier available to play for free during ~most~ villain phases. Great card!
