I just realized that we won't actually get enough Special Exchange Tickets from the Anniversary Countdown Daily Rewards.
We only get 2 of the black and white tickets a day and the total countdown rewards only lasts 42 days, so we would only have 84 total, of those tickets by the end of it. This means we cannot buy out the whole exchange items shop.
Then I guess the only exchange items to aim for would be the 1 Venus Gem, 5 Random Space Cards, and 5 Retrograde Cards. And we won't be able to clear all 3 items either since the Venus Gem alone costs 42 black and white tickets which is kind of insane.
The rainbow tickets are a separate counter and we will get enough to get the 5-star selector eventually.
Does anybody know if we somehow can get more black and white tickets during the upcoming events or is there some other way to buy out the whole shop? Or I guess we cannot? Or do leftover rainbow tickets convert to black and white ones somehow after we get the 5-star selector? (No idea how it worked on the OG Asia servers)
