Is paul greens jeopardy good for stage if your using a huge piece of paper and the predictions on that

I'd be less concerned about the paper being big and more concerned about the fact that the audience can't see the cards.

I guess you could do it with jumbo cards, but it's just not a stage effect.

It depends on how large the cards are, how small the stage is, and how well your audience can see.

This is a close-up effect. Paul Green is a close-up magician. That's what he designed his effects for. Most of his stuff is well suited for the restaurant environment (which is what he designed it for). So that being said, no. Jeopardy is not a stage effect.
