This is a deck idea for the future release of Jean Grey, I think utilizing the 3 card combo of using Jean Grey to a location hoping that an opponent leave 1 of the locations empty, you can Spider-man the empty location into Professor X to win a free location basically on turn 3 if you have the cards! Leaving Cerebro/Mystique on turn 6.
The deck currently runs 2 unnecessary cards in Bast which I know the whole deck is 3 power, this can just get Cerebro and Mystique up to that 3 power as well, so they can join the fun. And Valkyrie which has the same idea, if you have Cerebro and Mystique at the same location, you can drop Valk there to also pump Cerebro and Mystique.
Third theme in the deck is utilizing Scarlet Witch, Rhino and Magik to change out locations that hinder Cerebro and what the deck does...even though they are good locations! Locations like Muir Island, Nidavellir, etc. Get them our of here so your board can equally get the buffs.
*Honorable mentions*
The entire suggestions list is a nice tech sideboard, using a lot of disrupt cards and control cards...
You can utilize Absorbing man in many ways with this deck as well, you can Mordo, Debrii, Jean Grey...a lot of plays could be done with this build as well!
