One of the strongest Cerebro deck while remaining relatively consistent...Zero is a huge tech card for this deck idea, since you WANT to negate Titania or Lizard, and don't really card about Deathlok's effect since you usually play to empty locations. With Polaris and one day Silk, cards like Miles Morales get to be a 1 cost card, and so you can Zero Miles if you need to burn Zero's effect...That's 4 cards of your deck that you don't mind Zero-ing, which is a third of the deck, I think that's a fair ratio.
Omega Red, I feel is a no brainer, cause after Cerebro/Mystique, your cards will be a 9 power, which is insane and you should be getting Omega Red off, more often than not..and Doom is a 7 or 9 power to each location, opening up any location to house Omega Red's ability, just note that once you play Omega Red, opponents WILL obviously see your plays, so you could also drop Omega Red as a decoy to try to win the other two locations with your moving cards....
I get consistent wins with this online (obviously without Silk, and I don't have Polaris (I use Star-Lord & Warpath)) And its super satisfying getting huge boards with this deck!
*update with nightcrawler*
Nightcrawler provides a 3rd method and an easy turn 1 method to getting Miles out for cheap, I took out Namor maily cause the main turn 4 card you want to play is Omega Red anyway, cause after all the buffs, this deck consistently gets Red's effect off
*update (Jan 13th 2023)*
Sadly, Nimrod has been changed in the datamine from a 0/0 to a 5/5, so higher Cerebro builds have lost a strong Lockjaw fodder but luckily, with strong locations like Death's Domain and the new Altar of Death, Nimrod could find a home in Cerebro 5 as it'll be a mini Doom on 5 and then Doom on 6 and you can really fill your board with 5 power cards!
Mirage is an interesting effect, if the datamined effect remains when the card releases this will be the first of its kind, though it is kind of like Mysterio, its really its own effect...Disguising itself as another card til end of game, you could really trick opponents that you are trying to win left and right, by playing Mirage to mid (Like you would with Mr. Fantastic). My only gripe is that Mirage is currently a 4 drop for 5 which is VERY weak, even for what she does. I feel she should be a 3/5 since you'd mostly be playing Mr. Fantastic on 3 anyway (its really hard playing Mr. Fantastic any turn later, unless you are playing it on 6 in Sera/Surfer). But if she becomes a 3-cost (which if this be the case I'd swap Deathlok to side-board for Mirage), and her ability reads as it does, then you're opponent will be seeing a 3/2 Mr. Fantastic, til end of game and the surprise that you now have not just a 5-powered Mirage, but she'll be boosted by Cerebro and possibly Mystique too! Crazy!
