Danger runs Deep
All characters who (currently) identify as male remove two end-of-chain followers of their (the target’s) choice from their coalition and move them to discard.
“Danger Runs Deep” is the tagline from the 1995 Red October knockoff film Crimson Tide.
Wave of blood getting off the elevator on the ground floor of the Overlook Hotel is a reference to the 1980 film The Shining. And other films as well.
