I've been waiting for the Fake Ascension event and saving my cards for MONTHS!!! Right now, I have 90k black cards. As soon as Luna's banner appears, I'm gonna spam that fock'n gacha button, trust me! With all the cards that I saved, I really hope that I'll at least be able to SSS her!
Edit: I was able to get Luna 5 times with 90k cards. I was able to SSS her, but not SSS+ her. I think I'll spend a bit on the game on my next paycheck.
