So, just to be clear, this game has no turn structure, no resource system, no win condition, and everyone always has exactly what they need in their hand?
An actual game of 1000 Blank White Cards would have a turn structure, but this one doesn't to allow people to join in.
The stock 1000 Blank White Cards would not have a resource system, but a variant could easily have one.
1000 Blank White Cards is more of a fun game, technically the winner is the one with the most points.
And the whole reason it's called 1000 Blank White Cards is that you draw your own cards when you get them. In later games, blank cards can be mixed in with the previously made ones (unless they were denied).
