Candidly, if you like Paperclipped by Jay Sankey you probably don't need Bulldog.
The idea is new though. There's a part with Sankey's version where you have to get rid of a special something after the prediction is introduced. This is completely eliminated with Bulldog.
In Sankey's version, the paperclip cannot be examined, in Bulldog the clip is fine but one of the predictions cannot be examined.
Then there's the part about how Bulldog must use 2 predictions to work, Jay Sankey's only needs to use one. This can be a good or bad thing depending on what your needs are as a performer.
