Dont ask its a secret!) The Dark Illusion booster set contains 100 cards: 48 Commons, 20 Rares, 14 Super Rares, 10 Ultra Rares, and 8 Secret Rares.
Given how expensive the sets are, there are no doubt plenty of fans who wont take kindly to paying out for a bunch of images they might already own in one way or another
From a financial perspective it is a useful exercise to try to forecast which cards might be included in this set so that you can decide what you might need to do about it
You can only use each effect of "Shamisen Samsara Sorrowcat" once per turn
These groups purely exist for collectors to come together, show off their collections, chat, and of course, buy and sell Pokmon cards
Please be warned that Im about to delve a bit into statistics kindly get some tissue if mathematics makes your nose bleed
