Plot Screw

''So... Plot Hex Machina?''

A Plot Screw is when an UnTrash is played out of nowhere without any (clear) cause to put our main character(s) at a disadvantage. UnTrashes considered to be Plot Screws are Blocker Train and Hex Machina. Many Plot Screws can also be considered Eye Roll UnTrashes.

A Plot Screw is a type of Plot Saver that, instead of helping the characters, harms them by throwing something inconvenient in their way, like a dragon that keeps them from reaching the Grand Prize as they're Mere Moments Away from getting their hands on it. Plot Screws make characters delay their plans or maybe even be enough to force them to cancel those plans altogether.
