Let's just start by saying Cerebro, Mystique & Onslaught at 1 location can be pretty deadly on its own at 15 power, but this build kind of takes a different strat.
This deck is the start of the Lockjaw/Jubilee strat that helps bring higher cost, bigger powered cards to the board early, in hopes to build that bigger board presence as fast and plentiful as possible.
Having cards like Vision on 5 or possibly earlier is very strong! being able to every turn if let say you Lockjaw/Wasp out Vision on turn 3, you can bob and weave Vision to avoid Shang Chi (while under Cerebro) before it hits the board, and in general having a card that can reach locations like Death's Domain, Danger Room or Sanctum Sanctorum with minimal effort is always good.
Spider-Woman I feel is a staple in Cerebro 7 (until a better card may come along)...She already is a strong card, reducing power from your opponent's board, but also being able to be buffed in this deck just makes her VERY strong, and of course on Kamar-Taj or the two Sinister locations, Spider-Woman can be a huge threat!
*Update with datamined cards*
Stryfe isn't really a bad card, with Aero being able to pull your opponent's cards, or making big plays to make your opponent go to one location, Stryfe seems to be able to actually stick around, this could also be a solid turn 6 play, if you decide to drop Cerebro on 6 with another 3-cost, this could be a solid 3-cost to consider...if you were able to cheat out Onslaught, then dropped Cerebro where Slaught is and Stryfe to a location you know he will live (or under an opponents Armor) Stryfe can be an 11 power which is scary on that turn, cause a single card for 11 could possibly win it for you.
Stature, if her ability remains untouched upon release I feel is just another staple in the Cerebro 7 format. You don't always need to play Stature, and cheating her out is totally fine, but against Discardpolyspe or Hela Discard, which I feel will always be two decks you'll see on the ladder, Stature will be a powerful tech that'll allow your opponent's effects to also benefit you! Plus I feel like we all probably see Sokovia a good amount, well if Stature is in your hand on turn 1 and Sokovia is revealed, AND Stature survives, well you now have a 1/7 on turn one that's not Ebony Maw so you can still play cards there later, or even just Ebony Maw to have a HUGE location!

Holy Hell! The update to Aero is absolutely crazy and makes this deck just that much better...before this deck was just meh...Like it'll win, but consistently it had bad hands, but Aero is just too good, and if you Lockjaw or Jub, into Aero, you can really control the board to help set up the next few turns.
