Small Step, Giant Leap

Question : What happens if Small Step, Giant Leap is played during the tiebreaker?

Answer : As soon as the effect has fully resolved, yes.

Question : Can Celebration Day stop Small Step, Giant Leap?

Answer : Yes. In general, if an effect tells you to do something and another tells you that you cannot, the negative effect wins. Celebration Day prevents your Expedition from moving forward during the Day. If Small Step, Giant Leap is played on that Expedition during that Day, it will have no effect.
