>>4420231. Only focus on rolling for 1 boy if you want to spend as little as possible, does anyone interest you?
2. Prioritise rolling for his myth cards as those have important lore (you missed them all so far but there'll hopefully be reruns announced in the next big stream in jan).
3. Save your blue tickets for now imo, anniversary is in January and when Sylus released there was a special banner that let you pick any 5 specific cards to spook you, so you can splurge on that banner to get the myth card you want + any extra ones of the specific guy you choose
By the way, myth cards are the ones on the far right/3rd section in the "Falling for You" section
4. Abyssal Chaos has a lot of free goodies and should be quite easy to clear imo even as a newbie since the gamemode gives you maxed cards, even if you fail you'll get rewards so keep going until you max out the rewards
Thats all thats coming to me at the top of my head, I'll add more if I remember anything. If you have any questions also feel free to ask!
