There comes a point in many games of 1KBWC where an overabundance of cards becomes problematic.
Global Clutter[]
Think the opposite of the Thermonuclear Card Winter. This is hideously annoying. Everyone may have 30+ cards in front of them.
Score Clutter[]
At some point, the increasing point values that come with an increasing card count turn 1KBWC into a exercise in maths. If it goes on long enough, score values fly into the hundreds of millions. Cue the inevitable Rezero.
Hand Clutter[]
Probably the most annoying variant is when the majority of cards are cards you really don't want to play. This can be a result of low standards for cards to be kept in the deck causing deck sizes to explode over 400.
Blank Hand Clutter[]
This variation is when all your cards are blank, so you need to create a lengthy delay in gameplay.
