Sunspot (Cost 1/Power 0)
Armor (Cost 2/Power 3)

Doctor Doom (Cost 6/Power 5)
The Infinaut (Cost 6/Power 20)

Storm floods a location early, which means that no further plays can be made there, and Sersi is useless if she’s drawn late. Cosmo blocks her completely, which means no transformations are possible. Professor X gets the ability to lock a lane during the game. Armor shields important low-cost cards such as Sunspot from destruction whilst allowing you to stack Power safely in the relevant locations.
