Lucky! I've been trying to get her!
Well, admittedly, I resorted to buying her 😅 What can I say, I'd rather just pay $5 to get her (and then another $20 to level her up) rather than Gamble and HOPE I'd get her lol
I thought you can get by winning?
You potentially COULD, but Cream is designated a "Rare", so chances of getting her through playing are hard to come by. About the only reliable way to unlock Cream without paying is to open to golden chests, but even then it's a gamble on wether you get Cream or some other Rare, and you need to do that a bunch of times... So, I personally recommend just buying Cream while the opportunity is there lol Assuming you're able/allowed to
