Do Fair Prizes change every day? Or do they remain the same throughout the event?

New poll, pick your favorite :)

The Zeraora event needs to be tweaked.
You're telling me I've spent 17 days, an average of 4 hours daily, wasting 95k+ berries EACH DAY (which adds up to a total market value of nearly 5 MILLION PD in berry costs alone), only to still fall short of the plushies needed for a guaranteed shiny Zeraora egg? This is my first time participating in such an event, so I guess my opinion is irrelevant in the first place, but how is this considered fair in any way shape or form? If a person gives it their 100% participating in an event, should they not be rewarded? 💀
