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.
