you usually win them by being extremely lucky after probably spending a lot of credits, with no guarantees.
Actually, you could obtain 4 of the 5 special event cards when they were initially released without any luck at all:
- Niemira - 'Tis The Season: Reward for purchasing the Advent Calendar in 2017.
- Alyssia Kent - Splurging: Reward for collecting 10 stars through Black Friday 2018 promotions.
- Olivia Sin - Happy New Year: Reward for purchasing the Advent Calendar in 2018.
- Josephine Jackson - Tartan Cutie: Reward for pre-purchasing all cards to be released in April 2019.
Since their initial release, all of these cards have also been available through certain "game of chance" TGIF promotions like scratch cards. Ginebra Bellucci's Flash Flood card was released a part of a scratch card promotion in March 2019, so that one has always required some degree of luck to obtain. I'm curious what type of promotion we'll see tomorrow for The Black Fox card. (If I had to guess, it will be a reward for pre-purchasing all cards to be released in July at a 20% discount.)
