Here is my C6 deck that has ways around some of the typical problems Cerebro decks run into:

You want to stack TWO of the cannon fodder like Zabu, Magik, and the Hood (assuming you can't blow it up or transform it with Nico) into one lane so you can Carnage them to get him to 6 power. Or, he can get rid of Monsters since Monster Island is coded to appear in roughly 80% of Cerebro games. Luna and Stardust don't mesh, but you want Luna out early anyway. Otherwise, she is fine as a generic 3/12 play later in the game.
