The $20 pack has 30 tickets and 150 souls, that's the entire SP card right there without the randomness of the roulette. It doesn't look so bad if you're actually rolling to complete her (and not just trying to stock up on AS souls).
In the Halloween shop I picked up the set cards but I'm keeping the tokens for now, I'm waiting to see if I get lucky in the gacha with any of the characters, and I don't know yet if I'll bother with the option cards.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
