I’m personally a little reluctant to add any extra Battle Road data unless someone can chime in with a decent summary of how the Battle Road tournament stages actually worked. It’s hard to give a solid number on those cards as little documentation exists about the tournament structure.
A while back I updated the spreadsheet to mention the finalist React Energy and Rainbow Energy cards as having a distribution of “198?” along with the PCG-P Championship Arena as “288?”. These are the values I have personally concluded, but I could be very off with those.
If Championship Arena does have a distribution of 288 then the number of stamped Pikachu cards would depend on how many third stage battles needed winning before advancing to the fourth stage - if it was simply one win to advance, it could be said that the stamped Pikachu has a distribution of around 576 (288 x 2), however if it required more than one win to advance it would get more complicated for two reasons:
- How many people won a third stage battle but did not progress to stage four?
- Was a stamped Pikachu awarded for each third stage battle won (i.e. could individual participants be awarded multiple copies of the card)?
If it was a simple case of only needing to win one battle to progress then everything is dandy, but chances are it was probably a best of three - we’d then have to question whether the Pikachu was awarded to anyone who won a single battle or only to anyone who won the best of three. If it was on a per-battle basis, a result of 2-0 would result in one Pikachu being distributed to the winner (possibly 2 if the second point above is true) whereas 2-1 would result in both people being awarded copies of the card.
The same argument can be applied to the Championship Arena card as well - how many fourth stage victories were required to advance into the finals (stage 5)?
For the record, I have a thread asking about the structure of Battle Road tournament stages here: www.elitefourum.com/t/how-did-card-distributions-for-battle-road-tournaments-work/24911/1.
This card is certainly a candidate for a card which possibly has a distribution under 1,000, but I think we need more info before we can say that for certain.
